I have always been intrigued by the look and certainly the history of navy rail cars. Helium cars I recall seeing in the early 80’s at scale shows were somewhat crude and vey expensive! Alas I never acquired one. I somewhat recall there being a limited edition brass model, manufacturer ? They were very expensive and blink, they were gone! Anyone remember them? There are some modern kits available that look to be well researched (as seen on the bay). Made from Laser printed parts. ? Durability.
I have seen some vintage ones in tow on some of the vintage restoration locos videos seen here on this section of 2 rail posts , very exciting!
any photos or videos of yours appreciated.
thx.
