See attachment my father passed away in 09 and I inherited part of his collection. He called this one his goose gun. I’m looking to see what it’s worth is ?

Beautiful SBT. Not sure about the stock.

what does SBT stand for and the A1S on the gun it self ?

SBT= Single Barrel Trap. A1S is the grade. Which happens to be the highest grade available at the time.

I love the Unicorn.

Kenneth,
You stated earlier that the barrel measured 32". Are you certain? The Parker Identification & Serialization shows that the gun had 34" barrels. The book could be incorrect. A Parker Letter may resolve that question.

Also, the forend iron shows a "2" under the serial number. Would that indicate that there were 2 barrels with the gun?

I was thinking it might have been a two barrel SA-1 as well .

The other barrel is out there somewhere.
