I had posted on a italian gun earlier. I've not got a picture of the front of the barrels where they meet the barrel flats. This is Greek to me, but someone here can surely tell me what the bore diameter and chokes are I'm guessing from this information and what they are also proofed at. Want to know if this gun would be ok for normal hunting type loads. Thanks: Left Barrel KG 1,330 and 18.6 and 17.1 Right barrel Number 70 and then 20,3 and then 18.3 and 17.4 For the left barrel I'm guessing that the KG 1,330 is what it is proofed for. The 18.6 is the bore size left barrel and choke of that left barrel is 17.1. For the right barrel, I'm guessing 70 is chamber size. No idea what the 20,3 would be. And then 18.3 is bore size and the 17.4 is choke constriction. PS. If I'm wrong please correct me. This is an education process for me. Thanks

Left Barrel KG 1,330 (barrel weight = 2# 15 oz) and 18.6 (bore = 0.732") and 17.1 (muzzle = 0.673") That would give you 0.059" of choke constriction, which seems like way too much. Maybe I've missed something here.
Right barrel Number 70 (chamber length = 2.756") and then 20,3 (0.799" not sure about this one) and then 18.3 (0.720") and 17.4 (0.685")
For the left barrel I'm guessing that the KG 1,330 is what it is proofed for. The 18.6 is the bore size left barrel and choke of that left barrel is 17.1.
For the right barrel, I'm guessing 70 is chamber size. No idea what the 20,3 would be. And then 18.3 is bore size and the 17.4 is choke constriction.

I came up with the same as you with the one barrel. Choke of .059 which is the most choke I've ever heard of on a double. That said, my turkey gun has a bore of .729 and the choke tube is .665. The equates to .064, so I'm guessing anything is possible. Am surprised there is such a difference in the two bores.

Far as I know, on Italian guns, they do not stamp proof in kg or bars, as some proofhouses do (Spanish and British, for example). The pressure proofmark on an Italian gun is a star in a circle over PSF. If there are two of those, that's "superior" proof and you'd be good to go with any American factory loads. If there's just one, that's more the equivalent of standard CIP proof.

Hello Larry, Here are the action flats posted earlier: Couldn't the 20.3 be chamber diameter? Also, the kg in Italian guns refer to the weight of the barrels not pressure of proof. JC

Looks like the standard proof rather than the superior proof. I see only one mark over the PSF. Can't help with the 20.3.

the paper work that come with my B Rizzini indicates that the 1 star over PSF means it is proofed to 1200KG/CM the 2 star over PSF indicate 1370kg/CM Tut does your gun look anything like this

There are certainly similarities. This is also a guild gun with no markings on the barrels. Also, the area behind the fences is very different. Yours is a much higher grade no doubt.

I don't believe we've established a date on Tut's gun yet. The information I have is from a 1972 Gun Digest article, indicating that the standard smokeless proof (PSF indicating smokeless) was 12,000 psi. The superior proof, instituted in 1962, was 17,600 psi. Could be that the Italian proofhouse rules have changed since 1972, but if Tut's gun was made earlier than that--and there should be a Roman numeral date code--then I'd say the lower figure applies.

Found the date stamp. The gun was made in 1955.
