Vintage 1930's-1940's Hedberg Siren San Jose Cal USA For Sale

This is a vintage siren from the 1930's-1940's. Its stamped on the siren "Hedberg Sirens San Jose Cal USA". I don't know too much about it unfortunately other then that it was used on emergency vehicles. Its definitely missing some pieces / screws. I took a picture of all the loose extra hardware / pieces that was with it and what's still attached. Its missing some of the smaller flat head screws and possibly more. Not sure if this was ever attempted to be restored or if it was originally like it it. Some small holes and a couple small cracked areas on the siren itself. I tried taking as much pictures as possible to show current state. The siren does still rotate properly with ease.. To me it does not look in too terrible of condition considering the age. The brass / bronze clamp also has some minor chips / knicks on it with some minor oxidation. This could be good for a restoration project or just as a collectible piece. Please feel free to message me if you need more pictures or if you need measurements. I don't know if those two aluminum pieces stamped with signal signs LTD are for the siren but they were in the same box.
