[Milsurplus] Two B-Cs

Mini group & Group,

Maintenance and installation manual on RC-148-C is TM 11-1118C.  RC-148-C is 
for SCR-268-C.  Components are Interconector BC-1298, BC-1267-A, Power Supply 
RA-105-A, Rack FM-82, Antenna AN-128-A and Sig Gen I-222-A.  

Interesting section in rear of manual on Mark II, II N, III and IIIG IFF's.  
May be source of comment about Fighters under GCI control not using IFF.  Says 
Mark IIIG has addition GCI freqs and Mark IIIG was installed in Fighters.  
Table of equipment (aircraft and ground/shipboard), US and British, of the 
different Marks.  Nothing on Mark IV.

Nice manual, with photos, schematics, parts lists, etc.  The ones I have are 
all dated 01 December 1943.
