Horni Signal Mfg. Corp of New York

SCR-183 Wish List.

I'd like to find a good "grinder" with a 1930s order date.  

I'm also seeking some of the swapable tuning dials 
that fit the heads.  

I already have these:
MC-143    MC-144
MC-145    MC-186
MC-200

If you have any other dials or a 1930s grinder,
I have lots to trade.
