I was at a show yesterday and a vendor had a pile of various kinds of rifle stocks from 03's to synthetic ML to whatever. One of the stocks, however, was a very Mauser-looking stock complete with a mid-stock recoil lug and a cutout for your thumb when clip loading. It had a metal buttplate like the Turks and something I have not been able to ID is the sling bar it had on the left side of the stock. I looked thru MMOW (2nd Ed.) to no avail. The sling bar was squared off, protruding from the stock, no milled recess in the wood and seemed to have been pressed in as there was no protrusion or attachment on the right side and it did not swivel. The stock also seemed longer than a carbine. I'm going to have to start taking a tape measure with me in the future. Any ideas?
