You can go to BROWNELL'S Web Site and for a fee you can download the schematic and parts list for the 39A Marlin. Brownells or Gun Parts Corp. Brownells is always the better choice!
The correct answer is Numrich gun parts. Or, just google Marlin A1 schematic and it will show you a list of parts that you can order and a complete schematic to view.
Once you cross reference mod 42dl (Sears mod 103.19800) you will find your rifle is really the Marlin arms Mod 80. Parts are available from Numrich Arms at http://www.e-gunparts.com . Your parts and a schematic will show up under the Marlin 80. Good Luck Joe
Made only in 1979, the rifle is also numbered as a Marlin 49 or a Revelation 150. SOME parts are similar to the model 60. gunpartscorp.com (also known as Numrich) has SOME parts for the Marlin 49. If you visit their website, there is a schematic for the Model 49, with part numbers. You can compare part numbers with the Model 60. Same number, same part. Good luck!
