I think I may have posted some of these pictures in another thread quite some time ago, but since they relate to this thread (and I rediscovered them again) I thought I would post here.

This is only the second example of the buzzer assembly for the 2K1 WIRE 5 I have ever seen and Bill Gregg was kind enough to lend it to me from his collection in Rockwood many years ago to document. The lens cap is from a 58mm lens for scale purposes. For the record, there are absolutely no maker markings or numbers of any kind anywhere on this buzzer assembly, but I suspect it was a very common commercial item probably used in city street cars or buses prewar, or as residential door buzzers.

I will attach the first three pictures to this post and add a second post with the remaining three photos. This particular buzzer assembly came from a cab that had been painted aluminium inside late in life, hence the weird outer paint job.

The mounting block is solid fir, machined on the backside to match the inside curve of the rear cab corner, behind the co-drivers head. It is secured to the cab by two diagonally positioned hex head bolts which thread into lock nuts set into the two holes shown. The lock nut is still in place in the lower right hole. These lock nuts have a fancy name I cannot recall at the moment, and identical ones are used on the 2K1 Body to anchor the truss head slotted aluminium screws that help secure the roof assembly to the body sides along the roof line, just above the rain gutters. Last I looked, the nuts were still available from SPAE NAUR in Canada.

The buzzer is mounted to the wood block, terminals down, to connect to the wiring coming up from through the floor, that feeds back to the 2K1 Body, up through the conduit behind the front wall plywood of the body and out the passthrough to the lanyard switch mounted on the roof. And before I forget, the Signal Buzzer Switch and the lanyard loops are standard transit bus fittings commonly in use through the 1960's.

The base assembly of the buzzer is all black, with the exception of the circuit plate that is bare metal as shown. The buzzer cover plate is grey. Both colours are of a semi gloss finish. And that thing is loud!
