Yes, that's how I interpreted the numbering.

I soldered in a 1k resistor from the switch lug to the "ground" etch.? The receiver is working great.? I'll do an alignment on it next week and revisit why it makes the BFO function again.? It's weird.

If I am interpreting the dating of the schematics correctly, Garey's is later. (mine is 919664054 and the CD is 1026665400 and my C168 agrees with the CD.

I think you are interpreting it correctly.? This is what I think it means:

919664054 means 9/19/1966 at serial number 4054

1026665400 means 10/26/1966 at serial number 5400

So Drake discovered the error in the BFO schematic in about a month.
