I went with the 90L rifles because they are often un-molested and usually numbers matching. Seems like many of them did not get a lot of use in service, so were not subject to the normal changing of parts or FTRs like the earlier snipers. As a well defined group of rifles it is possible to see if there were consistencies and anomalies in the production, and as well the list could (and I have since learned has) be used to try and match up rifles with wayward scopes.
Yes, there should be lists for all the LB batches of sniper rifles. Perhaps start a thread on each. But I gotta tell you it is a bit of work pouring over the various sources to make up the initial list. Once done though, maintenance and updating is fairly easy.
