It gets better...
I searched on "Enjay" in the eBay N Scale section and found all five sale listings Michael mentioned.
However, there are three variations of the Enjay sticker!? There are "Vistalon," already mentioned, "Butyl" and "Chorobutyl".? $21 or $21.96 each... no thanks.
But wait, there's more... an "Enjay Promotional Set" which includes one of the A1G stickered boxcars, one of the Bachmann stickered boxcars, a Bachmann Santa Fe F-9, a Minitrix B&M auto rack, and an AHM Santa Fe caboose, plus a "Thunder Line" (AHM) power pack and track.? It also looks like there's a poster promoting / showing the flow of Enjay products to manufacturers.? It's quite the mixture of "Early N Scale."? I wonder how many of these exist, and I think now we know some of the origin of the Enjay cars.? $22.35 shipping from Michigan is a bit much...
Perhaps a footnote on the Enjay stickered A1G car is in order on the A1G website...
Cheers,
George (your list-owner)
