Standard Products Carbine

Found this locally appears to be an all correct Std. Products 2-44 underwood barrel , no bayo lug , rear flip sight , S J stock,
Not an expert on carbines any input appreciated
Thank you Attachment 52435

Depending on the serial number, the components are correct for a 2-44 rifle. The stock should have a crossed cannon cartouche on the right side butt, an SJ or S-HB inside the sling recess on the left side of butt. Wood not sanded. The buttplate will have a S-S3 to the left of the screw. Rear sight will be staked on the right side with a thin chisel mark only (no punch staking on front and rear of dovetail). The rear barrel band is unmarked. The front sight will be marked with the letter N or SN. Very important that the end of the muzzle be free of any scratches. This is a tell-tell sign of front sight removal, to usually take off a previously mounted bayonet lug. Look at the barrel for a shadow line of one time having a bayonet lug installed. Your barrel date is correct for the low wood stock. Trigger housing should probably be brazed instead of machined.
Another thing to look at is the stock at the rear barrel band. Viewed from the top where the band wraps around the barrel and the stock., you should see only the indentations of the narrow band marking the stock, not marks from a wider band, like the bayonet lug style band.

The interior components are just as important, if not more so than the exterior. The most important part of the interior parts is the wear patterns need to match with each other. It's not necessarily important that every part be marked with a letter S, as many contractors supplied parts to Standard Pro. If you do disassemble, there will be letters and numbers stamped on the right side of trigger housing, bottom or inside of the operating slide box, side of receiver and bolt lug. It can get complicated very quickly!
I Hope this helps.
