No, I think we have pretty consistent serial number ranges for each of the changes that I've listed. They seem to be in both the R's and RS's - not that we have a lot of RS's to review. I was mostly wondering if I'd missed anything or not included something such as RAS's suggestion for rear sights. I'll put up what I have for serial number ranges in the next day or two, then Drew and Rick can correct me.

I think the commonly found rear sights would be a good notation to have for each of the versions, don't think it should change the versions.

I considered listing the Winchester cartridge/900,000 serial number range RS's as another version since the receiver was changed.
