Re: any info on my .30 cal winchester carbine
Sounds like a late-war production Winchester M1 Carbine. A lot of carbines have popped up latey on this forum, and about alll I can do is give you the 'canned' answer. Looks like your Carbine is a re-import from over seas("Blue Sky"), and it is one of the vast number that went thru post-war re-builds (rock-ola barrel).
Winchester M1 Carbines are prized over the other 9 or 10 WW2 makers to collectors, but being what purists call a "Mix-Master", the value drops into the shooter category. There are people who re-build these rifles with 'original parts', but collectors frown on this.
As a shooter, my guess would be $400 to $600 in value. If it were an original with all Winchester parts, the value could double that. I'd leave it as it is and enjoy shooting it. Have fun!
