Another example from the same period but interesting that the left chamber is 65mm while the right chamber is 70mm.

Raimey, question, if the chambers on that gun are 18.7mm=.7362 inches, would you have to have the chambers opened because todays brass,zinc, head is measuring between .738-.742, resized and could be .740-.744 un-sized. I would imagine that earlier European shell heads were smaller.

On the one I was looking at converting 19.0mm is .7480 and that is larger than L.C. Smith chambers at .745.

JDW:
I'd want some ground truth on it, i.e., actual measurements and try some of the 65mm cartridges that are out there. I measured a few diameters and you are correct that the average floats arond 0.740". I've seen some very tight German chambers but none that wouldn't accept production cartridges. Now this is with the exception of early 10 bores with current RST production where the brass seems just a tad large. I wouldn't consider opening the chambers at all though.

What's the weight stamp of the barrels? 1.278 Kg?

Raimey, you might have misunderstood, the chambers on the gun you posted were 18.7mm which equals .8362. The chambers on the one I am looking at are 19.0mm=.748
I measured some Gamebore 16 ga and the hulls are Cheddites. They were fairly consistant at .741. Loaded shell measured 2 1/8" with a fold 6 crimp.

I won't get a chance to look at it today, maybe later this evening before they close, and I will look at the weight stamp.

Yeah, I'm con-fused and will have to located my calculator after I see what the ducks have to say about it. Does 18.7mm = 0.8362"?

I think it is a neat example by the way and you should let it come home with you.

Now, I'm getting dyslexic, 18.7mm equals .7362, that's what happens when you type something and don't proof read it. I typed it right in the first post, but hit the 8 instead of 7. Sorry.

I have a French sxs that is a little tight. I have to use Fiocchi hulls in it. I shoot Polywad vintagers in it, and they load Fiocchi hulls so it has been no concern for me.

The 65 indicates 2 1/2" chambers.

Went over and picked gun up. The markings on the barrel "Fluss Stahl-Krupp-Essen, I'm guessing mean Fluid Steel. Few markings that were small, looked to be a crown with LC under it, star with x under that, star with M under. Also what was covered with grease and hard to read P 1 K 278.9. Raimey mentioned that in his post and I guess that means weight of barrels at 2.818 lbs.
Gun weighs 6 lbs. 1 .8 ozs. 1 1/2" DAC and 2 3/8" DAH, 14 1/8" over 1" recoil pad. Checker is 24 lpi. Original choke markings were 16.4/70 (.646) right barrel and 16.6/70 (.653) left barrel. The right barrel is now .005, so .010 removed. Bore 17.0=.669 reads .672 on bore dial gage.

Again thanks to all to greatly helped on this. Like I said, I am a sucker for small bore guns, and my main interest is "elsies", but couldn't resist it.



Sounds like a good all around upland bird gun.
