Just reading David’s book and I concur with Calhoun. The 36xxxx is to early for checkering. Maybe I misread it.
Was checkering an option for the EG prior to 1940?
Thinking about making an offer for all three, maybe get a deal.
Looks like it might be 393xxx; EG checkering seems be stanard starting in the 38x,xxx range, but a few seen earlier than that.. Spiegels were being checkered as early as about 36x;xxx to end of Spiegel production, so I could see where some checkered stock/forearm EGs could have made their way in earlier.
