I haven't seen any written comments concerning interchangeability however it has been my experience that when the same (or similar) model of gun is made over the course of ten years or more, the longer the time difference between when the parts were made makes it less likely that they will interchange. Not hard and fast.
Glenfield Marlin Model 25 rifles were patterned after the Marlin 80C and Marlin 780 rifles. The Glenfield name was added for sales to coast-to-coast chain-stores versus stores that were specific Marlin dealer stores. The Glenfield 25 was manufactured from 1979 through 1982 according to Brophy. Others would suggest the Marlin Glenfield 25 was produced from 1972-1982. Regardless, the Glenfield name was dropped in 1983. The rifle continued as the Marlin Model 25 until 2003, which then became the Marlin 925. Differences between the Marlin and Glenfied were purely cosmestic i.e. birch stocks instead of walnut stock, different trigger guards, and triggers (black instead of gold colored). It is still being produced in .22LR (Marlin 925) and .22 Magnum (Marlin 925M) versions today. Most parts between the Glenfield 25 and Marlin 780 will interchange with no problem. Some of the Glenfield 20 and 25 will interchange as well. However, not all late model parts between the Marlin 780 and Marlin 80 will interchange with those models made in the pre-70s.
