Reply to "Whose freight car trucks are these?"

All are atlas/PRB, except the top right...pic not close enough to tell.

None will work on weaver cars correctly, unless u cut out the portion of the center sill at the bolster on the weaver cars....any you'll have to glue the rest of the center sill and braces on the underside back on....at least for weaver box cars.  Other weaver cars can be more of an issue..
