[ARC5] BC-458 and 696 parts question..

[Robert Downs]

Yes, all of the ATA and all of the SCR-274-N transmitters use the same A.R.C. part for the scale over the roller inductor.  The only difference was that the plate that holds the scale was unpainted on most of the latter.  AN/ARC-5 transmitters used a different part, although the engraved scale is probably the same.

Aren't all those using the same window scale?  I googled some BC-457 -458 -459 -696 images and they all seem to have the same scale on them.  I have a BC-459-A with a good looking scale in the window.

Does anyone in the group have a good, unshriveled window for either of 
these two transmitters and would be willing to make some measurements 
and photos? I have a friend that thinks he can make a set of molds on 
his laser engraver if I can build up a set of drawings. Every unit I've 
come across in the last few years has had a distorted window, so decent 
measurements were not possible.


Thanks,
