Gentlemen, I have a Smokey R51, G2 from Huntsville and its #H014XXX. I saw post on members "Sebvox" and "R51FAN2017" about serial numbers and wanted to put my 2 cents worth if they are building info on serial numbers. Just curious about the date and month mine was made also but really just wanted a Huntsville gun and it was important on the purchase and then I just thought it would be easy to find the serial number breakdown o the net and it turns out to be harder than I thought. The G1 had issues and I feel bad for Remington and the stigma that started to get out there but still wanted one if they worked it out. Thought I had time and then the plant started to close. I finally found one and mine does not fit into your number ranges from the comments unless I'm seeing it wrong. I asked a friend that uses a certain gun dealer that handled those guns and he mentions that all of the R51s frames, some were made in NC or Huntsville, "stamping" a Huntsville gun in NC but assembled in Huntsville. Not sure how accurate but he said if they have the H on the serial number its a Huntsville gun. He said all the smoke ones were marked HSV but they used the same serial prefix across both locations? My co-worker has a new gun digest book and he says all R51G2 Smoke guns are from 2018 thru 2019 and I think from Huntsville. I haven't seen the page he was reading from but could scan it when I get back to work to confirm that smoke is only Huntsville but I think I have seen a post of a smoke that was from NC? I just wanted to mention that mine was a different serial number range from the post back in April from "SEBVOX" when he was trying to compile a list.
Hope this helps or starts more comments on finding out the facts.
