This may have been covered in another thread.

As I understand it the 1865 trapdoors were converted from Civil War rifles -- new hammer, brazed liner to the barrels, and 1863 model locks.

The 1873 Trapdoors were completely new made.

The 1868 Trapdoors were mostly made from new but a few used locks and other parts converted from the stocks built during the Civil War.

Two questions --

1.) Am I correct or in error on the aforementioned beliefs re Trapdoors?

2.) While the 1873 Trapdoors were made from new, did the Springfield Armory use the old machinery for the locks and possibly stocks that they used during the Civil War?

Have looked on line but fear I haven't found this information. Not necessary for me to know but I would like to fill this gap in my knowledge.

Thank you.
