Might as well add the missing pictures I promised for the IMI and one that I got too..
Also, slight correction but it's not a "DDR siren", IMI actually was a Hungarian company.
For the Type 80, right now it's unfortunately bored (Klaxon unfortunately cut so many corners compared to the Type 77 and 72 that the T80 feels cheap as chips), the shaft was bent and trying to fix it I ruined the brushes, I'll make a separate post for it.
So far here's for the IMI, in no particular order

Another obscure siren arrived too, it's an Elektror S0, but the newer variant that was made by Funke-Huster (just before it was relabeled the FHF F0).
