They look like the old Roundhouse/MDC 34’ overton cars. The Athern or Horizon Hobby sites may have the parts listed. If not, some brass wire & a lot of patience will be required![:D]
If you don’t have the wire end rails and brake wheel/ shaft, they are easily formed out of brass. You may consider fabricating them anyway. The origional MDC ones are rather plain.
Thanks Bob, I believe I will try it. I got this photo from the Roundhouse site…
and it sure looks like mine…
Mine measures 35.5 scale feet with my HO ruler so I guess that is close enough for Roundhouse to call it a 34 foot. I want to add the green tinted windows at the top and window glazeing on the bottom ones also.
