Can anyone make a comment on this supposed 1847 Walker Colt ? It is marked on the left side; "D Company No.32" ......twice only....on frame under cylinder & just above barrel locking wedge. However, it has s/n: 1826 marked in 4 places (that I can see...) on the underside. Also, the gap between the barrel locking wedge and the bit just above the loading-rod seems a lot wider than many Walker photos I've seen....... I suspect this is an aged 2nd Generation Walker.
