SB Trap Bore and Choke Questions

[PAUL PLUNKETT III]

Was wiping down a few today from the safe and measured bores.
SN 238162 SC 34" bore .730 Choke.036
SN 225127 SC 34" bore .731 Choke .031(Extended Forcing Cones)
SN 232323 SC 32" bore .732 Choke .033
SN 206107 SC 32" bore .729 Choke .036
SN 190625 SA1 32"bore .742 Choke .044 (Upgrade by Delgrego and Runge)

I feel 238162,232323and 206107 have untouched bores.
225127 has original bore and choke but forcing cones have been extended.
190625 has been upgraded (1972) and most likely had bores polished.
Hope this helps Paul
