Okay, I've mostly got my mid 80s KHS special figured out, and I know my wife's '77 sekai sprint 1000 is decent enough for what it is (and with all original components minus bar end shifters and new bars)- pretty sweet ride, really.
Here's what else I've got, and I don't know a lot about some of these- (n my 21 inchish size range unless otherwise noted)
Unknown serial number old fuji Special Road Racer, frame only minus forks. (actually, the sugino bb setup looks original, and is pretty smooth). It's white with black highlighting at the lugs, old enamel fuji headbadge, chromed stays, and I can't find a serial number.....
Bridgestone City Limit. needs a thorough going over, but all bits there except seat.... Serial is 9KG24452. It's red. Seems nicer than any of the ATB type bikes I've tried riding, but I won't know until I get it tuned and ride it. Might be a keeper.
Peugot UO8 frames. 3, ranging from 71 to 75. I pretty much know about these, but the values on the intarweb are ALL over the board.
Old Raleigh Sports (malaysia production?) all there except the wheels, but I've got some, and 4 or 5 SA AW 3's (someday I'll find an FM and a dynohub and my schwinn club racer will be complete). I like the whole idea of the roadster, but never have had a decent running one (I won't count a Schwinn Breeze as decent by any stretch,nor a murray anything..) No obvious serno, and it's going to need a complete painting and such anyway. I may restore as a riding bike, but I won't go for original decals or anything.
A Lotus 2000R "pro series". I haven't met anyone who actually has heard of these, but the intarwebs claim they are pretty sweet ride. Currently set up with a 3 speed coaster brake conversion for lots of short quick riding fun.
A Puch step through- kinda tiny, complete, even the foamy grips are okay. I'm assuming based on the dual levers and foamie grips that it ain't much, but it's not obnoxiously heavy or anything. Actually, it's pretty nice rolling stock as is, even without a minor truing and lube job. (I just tried it). Way too small for me, but pretty sweet. M-6-F6077
A Sekai 1500- ID0456 - All I can tell is it looks like original components except the front DR is an suntour xcm lite (rear is a 7-gt, just like the '77 sprint 1000)- but the wheels are missing *sigh* - oh, and it's a step through.
I won't even get into the Schwinns. I've got let tours, super le tours, and even super le tour 12.2 frames (being built with a shimano 7 speed), a world traveller, a varsity, and that weird ass tourist model with the freewheel in the bottom bracket.
No real gems, lots of rideable fun, but some mysteries in the history.
