New Haven's PS-1 boxcars were prone to resale.

Examples of ex-NH 10'-0" inside height PS-1 boxcars were the first blue Port Huron and Detroit boxcars, and the yellow with red lettering AC&Y boxcars.    

Others went to DRGW, LV, CNW, TPW, WAB, and LNAC, I think these were 10'-6" inside height boxcars, hence road names for the new Kadee 1947-vintage tooling.

Were any of these 1950's sales?
