The 4E on the stamp is a date code. That could mean May 1954, May 1974 or May 1994, assuming this lamp uses the Philips date code system (some other manufacturers do). As to the power rating, 33W lamps are commonly used in incandescent text/advertising signs. Judging by the filament, this is likely a decorative lamp, the oddball power rating being to get a certain amount of light at a given design life (likely to simulate a 16cp/~200lm carbon filament lamp).
I know it's not the original from Eddison, but I cant find a store, online or not, or any references to when a 33W bulb was produced... I fount it in a about 100 year old house...

I knew it wasn't from edisons time.... I found it in a basement in a pretty old house. Older than the electricity has been around in my town...
