Clean it and shoot it. Coil springs very, very rarely wear out. If you replace parts it probably won't hurt anything and it's your money. I have a 1976 Wingmaster, and have had 5 others, and have yet to replace a single part. I have seen lots of 1950s guns still going strong. Until something quits working right, replacing parts is a crap shoot. Say there's a 1 in 1,000,000 failure rate on all parts. All the parts in your gun have already been tested out. New part may be one of those ones.
If a shell latch comes loose you can save yourself the trouble of going to a gunsmith by just glueing it back in with a little dab of two part epoxy between the holes. Only needed when cleaning anyway because the trigger groups holds it in place in use. Browning leaves theirs loose and just says don't take it apart.
