Add to say, just because there was a known 1860 Colt revolver in service with D Company, 2nd. W-VA Cav. only one number away from your revolver doesn't mean your revolver was even issued. It most likely was bought by the Gov't, but records are spotty at best. Surviving records state that sr. # 16370 was the earliest issued to the 2nd. W-VA Cav. and the latest, sr# 68569. That's over 52,000 revolvers issued elsewhere. Co. D 2nd. W-VA Cav. just happens to have the most complete record between those numbers accounting for 63 of those 52,000 revolvers which shows how scant surviving records are.
