Regarding the oddball E-6--could it be after a major shopping, it was hooked to a PRSL tender til its regularly assigned tender was completed (or the tender was shopped but NOT the engine?) You're right--all PRSL steam was 6000 series-with them being the original pre-PRSL WJ&S numbers. I'm willing to bet that wasn't a real PRSL unit. Wonder how they handled THAT one on the train sheet... or the orders and "A" card for that matter. Also regarding the PRSL group, I was a "charter member" before it actually convened. Some of you remember a fellow named George, who years ago managed the Lionel section of Ted's Engine House. I signed up thru him, but I don't ever remember a single meeting ever held. I lent my collection, glommed from the aftermath of the Coopers Point office fire, of every piece of original correspondence, from 1950 to 1965 between PRSL, the Budd company, the AAR, and about a half dozen other class-one's interested in PRSL's experience with them . Also were original PRSL press releases, press clippings, and other irreplacable documents. I lent them in good faith and to this day never have seen them. I don't know who kept them or if they were lost or discarded, but needless to say, that's quite a loss! If anyone knows of their whereabouts, please contact me. Thanks!
