Yes, the rho appears under the *S twice on the barrels so pretty confident of that now. Sequence of markings under left barrel is: weight,rho, *S, PV, Crown ELG *, 16/70 in an oval, and the same minus barrel weight under the right.

Should have mentioned it's marked 16/70 which makes it a bit more modern, not that I will shoot 70mm shells in it addicted as I am to 65mm reloads. Barrel weight is marked 1 k 272, and if my scale is right the gun comes in at 5.25 lbs., which for me is even more reason to use low pressure shells in it.

The PV mark is a Lion Rampant in outline over the PV, which makes it before 1959 I believe, but that isn't necessarily definitive for dating.

My choke gauges are elsewhere so can't check to see if the chokes are original but they look externally pretty close with the right a tad more open? I'd assume something like IM and Full or Full and Full, but that remains to be seen. Bit too tight for my taste and bird gunning at this point, but could work for ducks with an ITX spreader load in the right barrel.

Someone took the stock mount for the sling off so will replace that as I like slings and the wooden cheek pads...guess that's why I have a number of European doubles.
