This brings back memories of the Canadian RCA 5T5 and CGE E-81 sets I have owned and worked on, those were somewhat newer then this set though as they were 1936-37 models, but with those the bottom was made up of three pieces, two L shaped steel end plates one which the chassis mounts were riveted, and a thinner sheet metal cover for the bottom center. To get at much of anything the end plates had to come off. The bottom of this T7-5 chassis reminds me more of the Victor 118 I used to have and the CGE M-61 I currently have, which were 1934-35 models, I can kind of see the evolution of RCA/G.E chassis design here.
Regards
Arran
