Hi indynotch50.....welcome to TFF.
Well.....it's not listed in the Blue Book of Gun Values or the Standard Catalog of Firearms either.
The Blue Book does
list a few "Special Editions", but none with a synthetic stock. Yours may be a non-listed Special Edition or a Custom Shop gun, or ????????
I'd say your gun is a candidate for a question here:
When you get an answer, please let us know what it is.
