Thinking out loud here maybe a separate section for this with a running thread for each type (original configuration 1 rifles and 2 carbines, 3 sporters and unofficial modified, 4 receivers and barreled receivers.
Do not know if it is possible but one could wish for these threads to automatically put the serial numbers in order. I like Culpeper's table, owner could be KCA member, web, advertisement or other.
Maybe software capable of being combined into a single master list?
