It is a product of Al's Kustom. The P&W was his private road. IIRC he produced a set of three different road numbers, plus an car with no number. I have them (in storage); if you need more info I'll dig them out this weekend. Al Taublib produced a number of custom edition freight cars. I have a lot of 'em - especially Virginian and Pere Marquette, plus billboards. I continue to haunt shows and auctions looking for others. Last time I saw him, maybe 12-18 months ago, he was getting out of the business. I think job and family limited his hobby time. Al was a great dealer and model railroader. I considered him a friend; and I miss seeing him at shows.
