Mystery Bike!

So I purchased this off of craigslist today for $85, a steal in the Los Angeles area.

http://s12.photobucket.com/albums/a2...ystery%20Bike/

I can't find a logo anywhere on the frame to indicate what kind of bike it is. However, I have made a list of the components to help.

The derailleur's, shifters, and front sprocket are all Shimano, the front derailleur is a 600, I don't know about the rest.

The shifters (stem) are indexed, possibly Positrons?
Araya 27x1 1/4 rims with Sunshine hubs.
Raleigh seat
Weinmann brakes, Dia-Compe levers
Tourney crank

I didn't see a logo on the stem or handlebars.

My initial guess is a Suteki, however if this site is a solid reference then there are several parts that don't match up.
For example, the bottom bracket's don't match but are reasonably close.

So, any ideas?

Well, it is definitely a mystery, but here is my guesstimate. I think that it is a Ross bike, manufactured by Chain Bike Corp, in Bethlehem , PA. Two things to me indicate this: one is the welded on kickstand plate underneath the chainstays. Two is the rear brake cable housing braze-ons on the top tube. Ross had a signature type, and these sure look like them. They did make a model using these Shimano components, some upper end around $300 to $500. However, the stem looks French or Italian. Let's see what other sharp eyes have to say.

Also show pictures of the frame not the components. All the manufacturers used the same components in the same era at the same price levels. Roger

Positron systems were indexed at the derailleur, not the lever. Yours appear to be 'ratcheting' levers.

Alright, I put some more pictures of the frame in the album. Are there any specific pictures that would help?
