I bought this Sekine SHS270 today for $10.
Pretty cool with the dynamo lighting, fenders and saddle bag. The best part about it is that the seller still had the original purchase receipt!
It came from Victoria Sporting Goods (no longer exists) and was $224.95 before tax. Model number is stated as SHS270 and the serial number is 1005965. This is good for T-Mar's Sekine database, no?
Anyway, of course it fits into the usual "too small for me, too big for my girlfriend" category, so I think I will just restore it and keep it as a visitor's bike...or maybe sell it...
