Federal Signal Aerodynic PAR36 bulb question

edit-Found it, sure enough 4414 18w for flashers, 7610 50w for takedowns, and H7614 50w for the alleys. Flashers seem dim. Interesting.

I'm fixing up an aerodynic and the end PAR36s are all different. What was correct? I seem to remember there being different options but I can't find anything in a catalog or tech sheet. I saw 4414 listed once for the inner flashers of the aerotwin, that seems like a pretty low watt bulb for the end lamps.

1 seems too heavily fluted, it's 50w. 2 Seems about right fluting wise but it's 35w. 3 seems like the right fluting and is 50w.

Here is my work in progress replacing the broken off plastic speaker housing "feet". I'm using a 400 series blank insert from a Whelen edge 9M/Freedom for plastic parts. I still need to clean it up.

The plastic on the bulkheads is super brittle due to age anymore. I usually just glue what I can back together, until someone starts printing bulkheads.

As for lamps for the AeroDynic.. I have seen it all, typically flashers are 4414 but I have seen bars with all sorts from flood to spot. It was also common to run 4464 lamps for takedowns.
