    The 1946 Octal Model C is an identical case.

    There are four versions of same case with 7 pin mini valves (B7G tubes), 2 each of this 1947 C/A (No External Aerial/Earth) and the 1948 C/E (external Aerial/Earth option)
    1. Serial 56786 up to 100704 = Model C/A Different O/P circuit to C/E.
    2. Serial 100705 up to 125186 or 125185 = Model C/A similar O/P circuit to C/E but V4 g2 connected to HT
    3. Serial 125186 or 125187 up to 133899 = Model C/E but no R11 or R13, R11 & C20 connected direct to V4 g1 (control grid)
    4. Serial 133899 upwards = Final version Model C/E

    All versions use a B103 combined battery pack.
    The C/E has external aerial/earth connection loop on the frame aerial according to Trader Sheet. The Trader Sheet schematic and write-up shows the four variations more clearly than the R&TVS schematic
    The Model C/E was replaced by the Model K in 1949

Well, I knew from the advert it was a C/A or a C/E, (not Octal) but only subsequently realised how to tell a C/E (I updated the pages with what I found out!.

No one else bid so I got the radio at the very minimal asking price. The seller was honest.


One of the quite honest eBay photographs!

 

If you are of a nervous disposition hit the back button now!

Is it permissible to send so much livestock via courier from UK to Ireland?

The paint was holding that side together! 


The corner came away in my hand! Honest!

 

More...  Really leave now!


The base of the set came off!


Can you see them waving?

 

 

Curiously I could find no holes on the wood of the frame aerial. Well the Chassis and loop aerial is nice. Paint flaked and also purple from glue on the perspex.
