Serial numbers
CA 40723
CB55551
both .177 but one is a smooth bore version
Condition isn't the best but both shoot and have open sights fitted.
Blueing isn't very good ( not original)

I think the smooth bore is rare as I can't find much about them?
Also i can't date the one with a CB prefix serial number as there doesn't seem to be any date info on them?

Any info and a rough idea of value would be great

Merry Christmas!
