 This is just a quick follow-up to my video from the other day. This is Alex on this American series L50 Number of to to the guys were nice enough to forward me a PDF from a locksmithing journal from the 60s with instructions on This is something these things and how they how they go together So if you recall from the video I found this funny screw down inside the One side of this thing, and I thought it might be some disassembly thing, but it wasn't clear what to do So it turns out there's a little pin that sits in here Yeah, that sits in this space here. There's a little hole and it goes into a little groove in the plug And this little screw Goes down into the hole there and keeps that pin from popping out there by retaining the plug So to get this out on these locks, which are all that well, they've all been used a bit I took the screws out and the instructions basically said to take it with a rubber mallet and whack it a number of times To get the to basically drive the pin down that didn't work So I got up my trusty can of WD-40 sprayed a bunch in there Let it sit for a few minutes and then repeated the procedure with the mallet and sure enough They all popped open and so what I found and by the way, I do actually have keys to these I hadn't completely opened the box. They came in when I did the video but what I found is That you can now take the Plug out and you can see the wafer Tumblers in there. Let me get Well, that's okay Set that there and get a little close up of him That's a decent shot I think So you can see the wafers in here You can see the kind of action that happens as you oops Turn back and frame. Yeah, as you run like a rake Oops, if I can keep it from disassembling itself as you run a rake through it it'll lift up on these things and You know randomly bring them into position Now the key for this Looks like this Make sure I've got it oriented. Yeah Key looks like this number of people Sort of interested whether like it's a double-sided key. Well, it's sort of is But if you look carefully at it, it's it's symmetrical Right, so it goes down here. It goes up here, right? But it is true some of the wafers really the high wafers get pushed down or The wafers. Yeah, the wafers that are high Get drawn down by the bits on the bottom and the ones that are low get pushed up by the ones on the top So you do need both profiles to to operate the lock But the key can only go in one way obviously because of the the wards are asymmetrical But when the key is fully inserted into the lock Which is a bit of a there we go a bit hard for some reason when it's out Then everybody lines up and it lines up at the shear line which is Parent here you can see that big notch Big notch on each side. I think most of you are probably familiar with how wafer tumblers work The other thing I thought was kind of cool is the the interface so this is the end of the plug the inside end of the plug You can see it's got kind of a half moon shape here another half moon shape there and the tip of the key pops out and then See we get a little light in here There we go, you can see the engagement point There's a little tab that's at about seven o'clock and that's what the is all right Yeah, and that's what the that half moon engages with and that turns it around Now what's interesting if you look at this carefully and you look at the back of this carefully It's sort of analogous to Your monitor your other or the the pentum blur American locks where you have a Solid half moon here and then a quarter of a circle on the inside Right, and we all know that those have a vulnerability So I for for bypass because you can reach a wire a wire or pick in there and spin the Bolts around I suspect that this has a similar vulnerability. Although it might be a little harder. I don't know You can tell me but you might I think you probably could get something in the center there and And knock that around so it's interesting that they've had this same design property for Well, I don't know for a long time. Although some of these locks apparently were made in the 90s But I've got an older one here that has the same type of core I don't think I picked this one on camera, but it's the same idea. Here's its core I don't have a key for this one but Yeah, so and this this actually is pretty old because it has the junk Nuke brothers junk nuke brothers thing on it, so it's a little older It does not have a Date stamp on it, so I guess they hadn't started doing that then but has the same mechanism Apparently according to the article you could get various different Cores for this of different lengths and so forth or styles I don't know maybe different numbers of wafers in them or key ways So thought that was kind of neat. So then that little pin that I was talking about That retains the plug rides in that channel there. It's about 90 degrees worth of arc and Keeps the plug from coming out and then there's a little tiny hole Which if I focus and apply a bit of light You can see that hole there and there's a little tiny pin down in there and So you kind of tap that back into the groove Put the screw in and keeps the pin keeps the pin and keeps the tumbler in So whatever this design is it's pretty good. This this lock has obviously been in the elements a good bit It's a little bit Oops a little bit corroded Some of these well, yeah, it's weathered. Yeah, both of these are from the same lot The inside is pristine though. I mean the if you look at the thing. It's it's shiny. I haven't really cleaned this at all There's this older one was kind of gooey inside, but It's fairly well sealed up. I would say and the screws are brass Unlike the the like the 5200 where the screws are some kind of steel that rusts This is brass. This is brass the body is brass So you're not going to get any serious corrosion in there and it looked like You know it pretty much kept the elements out for a significant part So it's probably a pretty reliable lock. However, easy to pick it is So anyway, thanks the guys for forwarding that PDF Let me know if you want anyone wants a copy of it And it gives a breakdown. I didn't try to gut the rest of this thing Because I'm not sure I can get it back together reliably. So I'm gonna just leave it alone but and If anyone wants to fiddle with one of these I've got three of them, I think so Yeah, here's the third one here. So that one's shinier, but Yeah, so American L 50 series gutted and a little demo of wafer tumbler locks So anyway, thanks for watching and thanks for thanks everybody that responded to the previous post This is Alex have fun and stay legal. Thanks. Bye. Bye
