Great, thanks. Good link for dates of manufacture from that site. Know the fire was end of March 1997 (reason they only put out 500 in the first half of 97 I guess) and the easy opening change was with serial number 195,000 which was in late 1981, and according to my owners booklet the external manual firing pin selector was added to contender pistols manufactured after April 1, 1984 (somewhere in the 240,000 range according to the link provided by DanL). Still would like to put definite serial numbers with the changes so I know what changes go with each. I'll keep looking.
Anyone know what the last serial number made was?
Guess I'm getting down in the weeds, but "the devil's in the details".
