I lost two truck springs on an MTH ore car, sent an inquiry to MTH about purchasing replacements, no reply. I searched the NWSL catalog and found an acceptable replacement: #1402-4 Spring
Good info. I usually take them apart inside a clear bag. Assembly is done out in the open. A lot easier to see what your doing. Once I lose 2. I walk away figuring it's not my day. Every now and then. I find one under the bench while looking for something else that dropped. I picked up a bag of Weaver springs at at York which I haven't tried yet to finish off the few I have laying around that became spring donors. Good to know there's something out there.
Thanks Old Goat for sharing that information. It's alway great to learn about a suitable substitute for parts that may not be otherwise readily available from the original manufacturer. For example, I'm trying find the correct microswitch for inside S-Helper S-Trax turnouts/switches. So far I think this might be it https://www.digikey.com/produc...T/CKN9940-ND/2055218
