Okay, two more for the DB, both mixtes, bought a week apart in Ohio (from original owner) and Michigan respectively. First up, the one I would have thought was the older (and yes I know the front wheel's backwards):





Shogun 400, 19 1/2" mixte frame
SN S555534
Riveted headbadge, 'S' on seatstay lugs
Tange 900 frame, 'Tangaloy' fork, Tange headset
Sakae cranks, SR pedals
Shimano brakes, 'JD' code on calipers indicates April '85 I think ?
Shimano derailleurs, no model name
Araya rims on Shimano hubs, 6 sp cassette
SR stem, replaced bars, replaced saddle
