Gentlemen:
Please help me to find what I have in hands:
It is a Winchester model 101 and is marked SUPERGRADE at the bottom of the action.
The finish and engraving is like a Pigeon grade, but it has a straight english grip with double triggers.
The most interesting thing is that those triggers fires both barrels in inverse secuence, just like some Browning superposed models.
I can not find any description of those characteristics in the Blue book or Gun values reference books.
Could it be factory finished that way?
How rare it is?
Does it has a different value than a normal pigeon grade?
As always, thank you in advance for your advise.
Best,
