Belgian Browning A5 Proof Markings

Need some help from a Belgian A5 expert! I've located an A5 16 ga. in pristine condition, definitely bearing only Belgian origin markings, but there is a dilemna. On the left side of the barrel, it clearly says: cart.- 2 1/2, which I believe indicates 2 1/2 inch cartridges. On the string of other proofs along the left edge of the barrel, it also bears the greek symbol within which is: 16-70, which I believe refers to 16 ga, but 70mm (or 2 3/4 inch) cartridges. Is this a riddle? The challenge is, I have only 67 mm cartridges available here, so if it truly only accepts 2 1/2 inch shells, then I'm sunk. Also, on the bottom of the barrel is marked 16.6; which seems an odd barrel diameter to me, but perhaps it refers to a full choke? Please feel free to provide any and all expertise and advice. Thanks!

Hi Memo,

that's odd, in deed! Yes. 2 1/2 = 65 mm, while 16-70 is 2 3/4". Hum..... When was you gun proofed? There must be a date code letter, see here:

viewtopic.php?f=53&t=216472&start=60

I'd trust the proofs more than the barrel inscription. The officials at the Liege proof house don't tend to make mistakes. In any case: usage of 67 mm longs shells is OK, as these were made to fit both the 65 mm and the 70 mm long chambers.

Hi Memo,

well.... a possible reason could be: in the time when FN switched from 2 9/16" to 2 3/4" some barrels were marked with the old chamber length but had in deed the new longer chamber length. That's the reason why I asked for the date code letter. It is maybe (!) a transitional of the early/mid 50s.

But I'm only guessing, as I have only poor knowledge when it comes to post 1945 Auto 5s.

My advise: ask your question again on the Browning sub-forum here:

viewforum.php?f=53

There are many fellow collectors present knowning much more about post-war Auto 5 but who are reading posts in the ID/value section not that often.

Regards

Martin

I salute the whole company of the forum. I have a browning auto 5 owned by my grandfather, he bought it used ....
Do you know to determine
the years of manufacture.
Thank you very much
(Incidentally, the barrel on which it was produced in Belgium, but I do not know if the gun was used if the barrel was taken and placed by another gun).The model gun is light twelve
