You know, the guy here that might know the most about this era of wildcatting singleshots is probably buckstix. You might PM him for his opinion.
Without getting out a book I can't say for sure but that may be a Unertl "Programmer", which is a pretty high dollar model.
Your trigger is not a single trigger, but a single SET trigger, which is a plus. Push it forward (hard) and it should click. Then try the trigger pull.
The lever is custom and not a plus in my opinion.
To me, this is an action and a scope. The action has two demerits (initials and lever). The rest - not of any value to me and most of those that I know.
Your scope may be worth more than your rifle (in my case that is a certainty).
Sorry about that.
