I would contact Marlin,s customer service dept.They may be reached through the internet.
The guide I use states it came in .22 or .32. If it had a 16" barrel, it was a .22, but longer barrels could have been either.
The 336TS (by my guide) was a lever action 30-30 Win. made from 1983-87. 6 rd. tubular mag. 18.5 in micro-groove barrel and weighed in at 6.5 lbs. Had a Straight-grip American walnut stock, and (depending on condition) brings around $400. Hope this helps you.
The Barrel has to be removed to replace it. Any good Gun Smith should be able to do it.
I assume you mean the cartridge guide spring. You will have to remove the barrel to replace the guide spring. The barrel is retained by a cross-pin through the receiver. This is a tapered pin and should be drifted out from the left side of the receiver to the right. If the barrel is tight in the receiver after the cross pin is removed, set the barrel in a padded vise and drift the receiver off to the rear using a nylon, or brass drift punch.
According to the ninth edition of Flaydermans Guide to Antique firearms it ranges from $950.00 in very good condition to $3000 in excellent condition. There were less than 5000 manufactured.
Marlin probably has one and most likely won't sell it to you.

Ranger 34 was a model of the Marlin Model 65/65A marketed by Sears. Marlin made this firearm from 1935 to 1937 and it has a value of $100 if in pristine condition: Standard Catalog of Firearms: However the Gun Traders Guide shows a 65/65E that was in production from 1932 to 1938.
1940-1965 according to the guide I use.
Under the lever
Absolutely not!
