Can anyone give me any info about this rifle? Grandfather in laws. Left me with about six rifles, but this is the only real interesting one. Can't find any that look like this with this carving in the stock. Year? Value? Rare? Decent shooting rifle?
It's a "Colt 57"...a one year only rifle (1957)...built on a FN Mauser action. They came in two calibers...both .243 and .30-06. They were assembled for Colt be Jefferson Arms or Kodiak Arms...same company but ownership changed...not sure which the correct entity that built the Colt 57.
These rifles were fully the equal of any contemporary hunting rifle available then. About 5000 were made then after 1957 the name was changed to "Coltsman" and continued on the FN action for a few years then production becalmed based an a Sako action. The Coltsman was available in more calibers, short-and long-actions and different trim levels. Roughly 10,000 Coltsman rifles were assembled. All are very fine rifles.
The stock work on your example was done after it left Colt. While that somewhat hurts the value it doesn't harm its utility as a fine rifle.
If the OP wants a correct stock they are sometimes found for sale on eBay. Otherwise any stock made for a FN Mauser standard action action will work. There are many, many options in stock design, materials and appearance for that rifle. It can be personalized to please most anyone.
