Abilene,
Are the images still not showing? If so what are you viewing them on, a phone? If you can't see them let me know the way they have you copy the link changed on me.
I think my world is level again...the last time we were talking about this was probably 12 or 13 years ago. You have confirmed what I believed then. All large caliber R-M and Richards II revolver and frames are larger. AND the Richards Type II no matter what the caliber are oversized. Only the R-M .38s (Navy model conversions) are the same size as the Percussion frames and cylinders. I am speaking in generalities, there are differences but not like the Uberti Richards Type IIs and the large caliber Uberti Richards-Masons conversions.
These are the dimensions from several of mine. Note there is a difference on several of my Navy model Percussion cylinders:
Thank you for all of your help and putting up with me.
