I believe you have a Crosman airrifle. the model is V350 made 1961-69. I suggest that you go up on the web and do a search on "Airgun repair" several places still repair old airguns.
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

Finding parts for a JC Higgins Model 44 DLM rifle can be challenging, as this model was produced in limited quantities and is considered somewhat of a collector's item. Your best bet is to check with specialized gun shops, online auction sites, or forums dedicated to vintage firearms. Additionally, you may find parts through manufacturers that specialize in obsolete firearm components or by reaching out to gunsmiths who might have the necessary parts or can fabricate them.
