Flaigs was a highly respected gunsmith located just north of Pgh. Pa. I have seen there work at various gun shows in the area and it was always high quality and commanded a premium price. In western Pa. owning a Flaigs built rifle was a sign of wealth, their work wasn't cheap. I once owned a sporterized Arisaka 38 re-barreled to 257 Roberts, not by Flaigs, it was a well built rifle that was very accurate. I just never could get used to the awkward safety, it was hard for me to operate. If you could handle one before buying I would recommend it.

I don't know if it's a "story" but, I've heard the one about a guy that bought what he thought was a Jap rebarreled .30-06. It turned out to be a 6.5-06 with original barrel and rechambered. He shot it several times with .30-06 ammo. Didn't hurt it at all.
how did he get a 30-06 to chamber in a 6.5-06??????
I recall Flaig's Lodge of Millvale, Pa from the myriad full page ads in such prominent publications as American Rifleman, Guns Magazine, etc from Fifties to ???. Them and Paul Jager No direct business with them, but all inferences accrued over some decades of quality rifle making. I have one of theirs likely was shipped out as a barreled action and stocked later as it's serviceable but bit clunky. A medium weight barreled FN Mauser in 7x61 Sharpe & Hart. Bought it really cheap as by the era I picked it up, that chambering was largely history and sustained primarily by a small group of Schultz & Larsen rifle enthusiasts - including me - of which it reflected was a principal chambering and I was 'long on such ammo. The era of mine was almost surely early Sixties also dated by proclivity for that chambering which never reached 'rotation speed' to get off the ground. Pix below.

Some of Flaig’s stuff was top of the line, other stuff not so much. I think your seller is trying to sell the name on this one - personally I’d pass on that one unless you could get it for much less…..and I like Arisakas. I have two sporters in 6.5x257, with Timney triggers and safeties installed they are very accurate with Hornady 129s.
I just looked at a early type 38 with a 257 Roberts chambered Octagon barrel on a Mannlicher stock. I shoot everything scoped and just couldn't see how I could operate the safety easily with a scope hanging over it. The price was good but as said earlier it might be a gun hard to get rid of if I didnt like it. If there was a way to get rid of the big knob safety on the back I would buy it but I don't know Ariskas and couldn't find anything on moding it.
