I can think of two methods that may yield a better result, are 'doable', but would perhaps be expensive / more difficult to arrange and either would require use of a 'loaner' magazine. One could borrow an M1910 magazine spool and:

A) Consult with a firm that does high quality 3D printed prototypes, have them scan the original spool and / or carrier / housing and have them 'printed' in a durable material.

B) Same idea, but contact a competent manufacturing jeweler and have precise wax castings done in bronze or stainless steel.

Either would provide the opportunity to recoup expense by having small lots produced and selling them to other MS aficionados.
