I recently purchased a double rifle retailed by Weisgerber in St Wendel via a Gunbroker auction. It arrived earlier this week.

Proofs on flats indicate bore of 0.340" or 0.350 since the gauge is 118.35. I hadn't used it prior to researching this rifle before bidding, but the formula for converting gauge to caliber is on Wikipedia at https://en.wikipedia.org/wiki/Gauge_(firearms)

The nitro proof mark is on the side of the barrels, not the flats, best seen in the pictures showing the sides of the receiver. The "N" is to the left of the "2.7 g G.B.R" over St m G (Stahl Mantel Geschoss or Steel Jacked Bullet). This is different than the mark for copper jacketed bullets, K m G for Kupfermantelgeschoss (if Wikipedia is to be believed).

On a different post here on Nitroexpress, Kuduae shared "It was proofed for a service charge of 2.7 gramm = 42 gr GBP = smokeless rifle flake powder. This was the contemporary smokeless load for the 9.3x72R with a 196 gr copper jacket bullet at 2020 fps. The 9.3x74R charge would be 3.5g = 54 gr."

Tinker pointed out that both triggers are single set triggers, where you push forward to set, reducing trigger pull weight to release. The front trigger is currently adjusted so these weights are fairly similar. The rear trigger has a very light pull when set.

I have not yet cast the chambers but can confirm that a 360 BPE (9.3x57r) case rim perfectly fits the chamber rim. Right now the 360 BPE cases I have don't fully seat, leaving the last 1/8" proud. Chambers are for a straight wall cartridge and fiddling with a dowel suggests this is indeed a 9.3x72r. I have some 9.3x72r ammo coming and will cast the chamber before using that.

Bores are shiny. Overall rifle is in quite nice condition and also surprisingly light weight, at only 7.5lb.

Will post pics below.

Thanks to folks that contributed to the post started by 85lc on this auction.

Also, if anyone has suggestions as to how I can scope this using the existing Triebel scope mounts, I would be grateful.
