Jason, I have good news and bad news!
The bad news is that we don't have any records for your gun so don't bother sending for a research letter. It also appears that your butt stock is not original however the stock looks very nice.
The good news is that Griffin & Howe does have information on your gun assuming I read your serial number as 190269 correctly. G & H, through acquisition of many large sporting goods stores over the years, has records of sale. Contact Bob Beach at G & H through their web site or

Nice gun!
