Doc . . . sounds like you had a good time and came home with your arms full! A successful day!
Is the C & B a Navy (i.e. Navy frame) or is it a .36 on a Army frame?
I don't know a thing about Mitchell but have a feeling you may be correct in your guess on it. Is there a date code on the revolver? Also . . what caliber?
And you know what they say . . "no photos they don't exist!".
Will be anxious to hear how you like the 4 3/4" barrel length. I love my 357 Uberti Bisley in that length.
Glad the day was fun and went well!
