Research letter & Barrel inspection clarification

[Rick Riddell]

cool! Thank you Dean! I know it's all speculation and the only info I have is two prior owners before me, so who knows what could have been done! I know it has 2 3/4 chambers now but wasn't sure at what extent Parker would have done during the barrel repairs and how that would affect our modern day way of measuring for safe tolerances.

I distinctly recall a previous thread regarding a gun that had been to Bachelder with 7" & 10" "forcing cones" and over-size bore. I believe the consensus was that the barrels had simply been honed. Can anyone else confirm?
Please share the wall thicknesses of the right .742" barrel from the end of the chamber out to 10".
