All my life I've been told that Marx 3/16' are really s-gauge on s-gauge wheels. I need a couple of covered hoppers that I can find in s-gauge and I can get trucks and couplers from Grossman and can convert them.
I have a couple of questins:
1. has anyone here actually done this?
2. does it look good?
3. what issues will I encounter if I do this?
Thanks.
