Run by of my RS-3L. This is an early "RS" horn, where the back heads have "Pat Applied For" cast into them, meaning the patent had been applied for but not yet given for the Leslie "RS" power chambers. This makes it a late 70s, early "RS" series horn. It is a former Conrail, CSX horn with builder's tag, and a low profile manifold. The bell arrangement was a standard 44 reversal, but I changed it to a 31 bell reversal with the 25 and 44 up front. csx700 is at the valve.
Yeah, there is a rip in the silicone cushion around the diaphragm, it needs a new one.

That's a neat reversal to try, but you might check that 44 power chamber. The 44 isn't sounding. Sould be awesome when it gets right.
