.220-250 by Chas. Tebor?

[Coyote3855]

I'm looking at a 1956 (SN 3738XX) Winchester Model 70 Standard Grade that has been rebarreled. The left side of the barrel just ahead of the receiver is stamped in two lines: Chas. Tebor / .220-250
The lettering is about 1/8 inch high, sans serif, and appears professionally done. No provision on the barrel for either front or rear sight. Excellent bright blue finish on the barrel that contrasts with the matte finished receiver. Receiver is tapped for scope mounts, but no scope present.

Google yields nothing on either Tebor or .220-250. A genealogical search finds a couple of Tebors, but no gunsmiths. Given the time frame, my guess is this may be one of the wildcats that eventually led to standardization of the .22-250? Or perhaps a post .22-250 "improvement"?

The firearm is in the collection of a local museum, so I'm only seeking information on the gunsmith or barrel maker and the caliber. It isn't for sale, of course, and I don't have the facilities or permission to do a chamber cast.

Thanks in advance for any information you may have, or any speculation you wish to indulge in.

Mods are free to move this the Firearms Research section if so desired.

Why is it in a museum?

It is one of about 24 stolen firearms that were recovered in 1975 and donated to the museum in 1979 by the United States Attorney who prosecuted the case. In 3-4 cases, original owners were identified and the firearms returned to them.

The vast majority of items in a museum's collection may have no particular historic or historical significance at the present time. Only 2-3% of items in a museum's collection are on display at any one time.

I don't know what museum you are talking about, but at the Rock Island Arsenal Museum we have all of our guns, 1216 of them, on display at all times. We had another 1300 in storage but the Army wanted them back so they raided the basement and shipped them all off to Anniston Arsenal and stuck them in a bunker. Maggots !!!

Wish they would have left us the 30MM Mk 108 cannon out of a Messerschmidt 109
