I have been talking to another forum member and some marlin experts on an old model 1936 that has been passed down to me by my great uncle.
I figured I would post what I have found out about my carbine incase anyone else is interested or has one similar to mine. There is alot of confising stuff on the internet regarding old model 1936s so I'm glad I could hear it from the people in the know.
I emailed a gun collector I know and he sent me this back.
"I am forwarding you a forum discussion relating to the Marlin Model 36 you have. It appears that you most likely have a Model 36 "2nd Variation" which has had the quick detatchable swivels added post production. Here is the link......

As background.... the Model 36 - 2nd variation has the "case" colored receiver (which your's has) with the inscription "Model 1936" on the upper tang. It has a heavier buttstock without the "fluting" seen in preceeding models. Additionally the buttplate itself is thicker and more curved that earlier models (made from hard rubber). As you already know, it has a "B" prefix in the serial number. It was manufactured in 1941.
The other alternative is highly unlikely, but close inspection would be warranted since it could place your rifle in a very rare group. In 1945 Marlin made 50 Model 36 "ADL Deluxe Rifle. Distinguishing characteristics are checkering on the pistol grip, buttstock and forearm; a pistol grip cap (plastic) and Winchester quick detachable swivels with a 1" sling. They also had a "B" prefix and had "Model 1936" inscribed on the upper tang. Because of the rarity, these are being tracked, and efforts continue to locate more of these in original form. So far only 15 have been found, and their serial numbers and ownership has been documented. Not unexpectedly, many efforts have been made over the years to "re-configure" the 2nd variations by adding checkering, and attaching quick-release swivels. Often times the swivels were those produced by Mossberg for their guns, and the wrong spacing or screws were used so the attempt to deceive was easy to detect.
In either case, your gun is a fine collectible. Whether you decide to fire it or not would be a personal choice - but you should first rule out the remote possibility that it is indeed an ADL..... If, after reviewing this information and that included in the attachment, you think it may be possible that you have an ADL, please contact the gentleman referenced and attach as many appropriate pictures as possible (swivels, checkering on all three locations, butt plate and flute area of stock)."
So I emailed the picture to the guy referenced in the article and who is a past president of Marlin Firearms Collectors Association and he had this to say.
"I wish that I could tell you that this was of the 1936 ADL Deluxe rifles, but I'm sorry it's not. First, it's a carbine and not a rifle. The sling swivels are the wrong type and there is no grip cap on the pistol grip. Someone added the checkering, but from what I can see from your first picture, the forearm is not checkered. It is a 1941 production carbine and it is the last year that Marlin case colored the receivers. Right after the war, the receivers were all blued. It's a very nice Model 1936 and one that is very nice to have in a collection.."
Here are some pictures.
I can't see the pics from here but will check them out tonight.
That's awesome!!! Keep that one!
Sorry I forgot I included them in this but the smaller pics are pictures of a verified ADL. You can see the difference in the sling mounts and the checkering in the forearm.
that was back when it was good ol U.S. steel, so different from what we have today. built by people with skills not mass produced by modern tech. I'll take an old model anyday.
