Umm, you know those were the ex-RDG units. There were only a few of them, and having more than one in New England at any time would be pretty rare.
And they're missing the RDG rain gutters.
Just a little reality check...
Hopefully though, they'll do the later phases for you. Ones with the bug eye class lamps, the anticlimbers, etc... I believe they were the pinnacle of GP development.
