Coffin magazine sorings

[USMCsean]

Has anyone ever encountered worn out magazine springs or missing floor plates for their coffins? 
 

I was digging through some archival drawings and found some original production drawings for the coffin mags. Was thinking of maybe finding someone who might be able to manufacture new springs or other parts.

New manufacture springs are available: https://www.bayougunrunner.com/SUOMI-M31-50-RND-COFFIN-MAGAZINE-REPLACEMENT-SPRINGS_p_1165.html

I have some coffins for my Lage 10/31k and replaced all the springs preemptively (also kept the old ones just in case).  The mags run great with the new springs.

I wasn't aware that someone made reproductions. Thanks for the link.

Is there any reason to keep the OEM springs?

Not particularly, no.  But the original springs lasted 70+ plus years and are probably still fine.  The new springs will likely last just as long but maybe they don't?  It doesn't hurt to have some spare old springs around.  Also I may be a hoarder. ?

You sound like me.
