In case you missed it in th "Exeter" thread Jimmy, with some editing -
You can usually find materials suppliers at these sort of shows and on-line that sell 12" lengths of compression springs, around 3 mm dia' that suit the" Aristo'" couplers, that you can then snip to length. Also pump action hand wash bottles and cleaning product "squirty" guns are good source of the right dia' springs too. That's what I resorted to, as they are prone to drop out, when I had Aristo' stock and no factory spares, handy items to have around. If my memory serves me well the same springs work in some Aristo trucks/axle guards and Bachmann locos for their suspension, where fitted. Then again some kind soul on here might have a few spares. Those cars and some other clerestory types made by USAT(Delton ?) are way nicer than the more basic Bachmann offerings. Max
Rhino - Aristo/Bachmann I can't remember, but not USAT. But I had a few cars supplied with those whe I started 15 years ago and was into mainly 1:29. Switched it all to knuckles though. Hook and loop never look right to me.
