(most parts were shipped together in groups, magazine catches with sears, etc) Here is some known shipments to Rock-Ola, how ever there could be more shipments that occurred that are unknown but this is a good reference. So don't get super disappointing if your Carbine is not all matching, its possible its exactly how it was when it left the factory!!! An example say Underwood was low on sears, Inland would ship some Sears to them. Just because its all matching doesn't necessary mean that is how it left the factory. ****** There is a difference between an all matching carbine and how it left the factory, a lot of M1 Carbine contractors shipped parts to other Contractors. All matching vs how it left the factory: Rock-Ola was more known for there Jukeboxes. Later Rock-Ola started meeting the Governments standards for quantity and quality. Rock-Ola only produced approximately 6,000 M1 Carbines in its first 6 months. Primary stock & hand guard supplier: Rock-Olaīolts, receivers, barrels, stocks & hand guards, gas cylinders, extractors, firing pins, recoil plates, trigger housings, sears, triggers and slides Serial number blocks assigned by the government: They made the least amount of carbines which is why they are more desireable. Approximately 228,500 total Carbines were made by Rock-Ola: About 3.7% of M1 Carbines made.-M1 Carbines 228,500 (Rock-Ola, did not make the M2, M3, T3, or M1A1 Carbines) Average Cost to Government per completed rifle, $58.00. Main Manufacture & Identification Codes: "R" "Rock-Ola" I don't have the bore or muzzle numbers, but have shot about 30 rounds through it without problems.ĮTA: I inherited a Rock Ola last year, this is some information i had stored for research. I believe this M1 Carbine was sent to be refurbished/rebuilt by Standard Products Company around the KW as it has the cartouche stamp of this company as well as a swivel safety, non flip rear sight, Bayonet housing, and 30 round clip support. the letters SJ stamped on the upper forearm stockġ0.the cartouche letters P-U stamped in the sling wellġ1.a boxed cartouche stamped STD over a PROD over a RWH in front of the sling wellġ2.a very faint cartouche stamped boxed GHD over a UEF with circled cannons to the right of the GRD over the UEF on right side of stockġ3.the numbers 4362840 stamped on left side of stock SN 249XXXX with underwood above the SN and a small w stamped on the receiver behind the SNĩ. 2 flaming bombs on the trigger housing one bigger than the otherĨ. a W1 stamped on the rear stock retaining screw housingħ. the letters JM stamped on the Bayonet SleeveĤ. a letter G or a number 6 stamped on the bayonet housingģ. Underwood 3-44 flaming bomb and a U stampĢ. Here's the info on the Underwood M1 Carbine.ġ. There realy isn't that many originals out there. If you want a collecter, buy from a well know dealer in original carbines.

So, if you just want a shooter, buy one that has upgrade parts. Some are not easy to tell from the real parts. You will find these on socalled "Original" carbines. Knowing all of what should or shouldn't be on a carbine will let you know if the price is a good one or not. Things like the marks left by once haveing a bayonet lug barrel band on the rifle or stake marks for an adjustable rear sight on early carbines. Only way to tell, is by wear marks and the color shade of those parts. A true unmolested carbine of ant maker is worth more than an assembly of correct parts. This has drove up the price of parts and increased the price of carbines. The last ten years or so, owners have been buying up parts and installing "correct" parts in them. Most carbines were rebuilt by the military. Also if it is original as issued or an assembly of parts. Value has to do with how many were made of each.
