Canvasback:
Skip that request as you've already supplied 238 & 39. If these are the final datastrings these passed only a few numbers apart. Tough to say seeing we are dealing with some bastard proofs being a mix of proofhouses/laws. Clearly the encircled bore/chamber data was not in the mix. I guess the Weipert ledger would answer all questions.

Kind Regards,
