What bsa is this

[edbear2]

I would venture that it is a hybrid. That barrel appears to be a (later?) replacement; the blueing condition is markedly different between the barrel and cylinder, cocking arm and trigger block.

Dunno........The proportions and bits all look correct for a BSA barrel of the original type, especially if you click on them as they come up quite big, then compare to other examples say on danny's site.......except for possibly a replacement rear sight insert. It is also quite common to get an original prewar gun with differences in bluing due to handling, ie. the compression chambers often have more patina than the barrel due to just more contact with skin, and photos are notoriously inaccurate to go by.

Just my thoughts, will be interesting to find out.

I Offered my Cadet Major up to my Breakdown today and without taking each apart to do exact measuring they do look like they would interchange.

The cadet only came in .177 as well. Though at least one barrel was made in .22 as Knibbs has one for sale.

So it would seem Cadet Major barrel possibly would fit & you'd be hard pushed to tell (or I would) but still doesn't explain why this one's a .22

My mate is on holiday for 2 weeks I will take pictures when he is back, there was bsa marks on barrel

New photos
Barral is a .22 smoothbore if that helps
Pictures showing stamps etc

It looks like a drilled out breakdown barrel, hence it being smoothbored.

It is definitely not a cadet major/Cadet barrel, as it has a spring detent on the barrel, under the breech, which is different from the Cadet design.

Must be great fun with some .22 darts.

My thoughts as well with the barrel being smoothbore, someone as drilled it out.

I would like to see that bore, as if drilled would be pants unless polished ........If the O.P. can clean it and shine a light and tell us that may be interesting!

I'm leaning towards the view that it was not available over here but made for export to somewhere like Ireland or even India?

If someone had the engineering capability to open that length of .177 bore to .22 in a straight and true manner then I'm certain they had the the capability to ream and hone it to size as well. Drilling it out to size might sound easy to a layman but in reality it is a pig of a job unless one is geared up for it.

My view is that it's a factory job for export. I too would like to see a bore view

What do other engineers think?

I wonder if Knibbs would have an idea anyone on here have friendly contact there?
