Early double marathon Santana on ebay
FWIW; There is an early double marathon Santana on ebay--bidding poorly and ending today. Its decal says its Reynolds 531 Tandem tubing which is interesting if true. Design, appearance and pipe sizing wise it looks just like the Jack Taylor's of the 1980-era (such as those sold by Bikecology at the time). Either way it would clearly make a great tourer.
Anyway it is in California and the seller is not able/willling to ship its so local pickup only... bummer. It is a shame there isn't a tandem shipping proxy service for the left coast!!
Hopefully someone will get it who isn't going to cut it up to make a beach cruiser...
