Years ago, many, many years ago now, I bought my first 1875, it was a Navy Arms gun in 44-40 and as best I can remember I was impressed because the serial number was 110. Now as I look back I have to wonder because it had the cross pin frame. Did Navy restart the serial number range? Were there frames that never got used and when Navy took over did they just got the cross pin because that was what was now 'normal'? Unfortunately I let it get away from me in the mid '80's and the GI I sold it to was moved to California so I can't pull it out to check. I wonder if it was one of the Armi San Marco 1875s and if they were their own serial numbers. I currently have 8 1875s but all are marked Uberti. The early history on the replica 1875's has always fascinated me but there just isn't that much really available on them. My earliest one, no. 10, has a date code of XX7 or 1971, and it is marked XX7 not XXVII, both of the 2XX serial guns have XX8 for 1972. My latest is from 2006 and is the long barrel 45 in the upper picture. No idea what the date code on no. 110 was, wish I'd kept that one.
