Marlin offered 9 different guns with the Royal Canadian theme. In the Model 336 line, there was the 336C or carbine (pistol grip stock) in either .30-30 or .35 Remington calibers and a 336T or Texan (straignt grip stock) in .30-30 caliber only. The Royal Canadian guns were sold through the Canada distributors and dealers. Any one of these versions are quite rare, especially the 336T. Some of the Royal Canadian guns had special high grade, Monte Carlo stocks and all had the Royal Canadian roll stamp on the barrel.
In 1962, Marlin offered owners of Marlin rifles to get carved stocks through regular advertising. It could be that your gun received one of these left over carved stocks or the owner sent to Marlin for one of the carved stocks offered at the time. The Marlin flyer advertising the Royal Canadian guns do not show a carved stock.
These are quite rare guns and are collectors items to those that collect the more modern Marlin guns. I would have to do some checking around to find what the value would be considered to be. I can tell you how many of the type you have if you let me know which version you have.
Looking forward to your reply......
Due to the increasing cost of ammunition, there be no warning shot!
