I figured 40' box=steam; but that's sorta maybe not true. I'm pretty
sure the cars I'm working with were built in the late fifties and may
have gone into the '80's, so I'll try BBFCL. It's a new group for me,
but it's nice to meet new friends. I might bring it up on MFCL, but
I've gotta check their "time span" first. Anyway, thanks to all for
your guidance on this.
