What a tangled web we weave when we buy from Ebay to be cheap!

OK, so I bought two 99" THK rails and never really checked them over good. In fact, one rail stayed in the crate till I figured I was ready to mount them. My bad !!! (but the picture on ebay,Sep-24-03, showed two rails exactly the same with bearings).
The four carriages (bearings) that came with them only fit one rail (hereafter referred to as the THK rail). So now I have this "Other" rail that is 99" long that doesn't fit anything and I'm missing one very long THK rail that would work with these carriages.

So now what to do. Any obligation the seller had has long since expired (again, my bad). But that doesn't change my situation. I have a 99" rail I can't use and have no idea how to look it up to see what it is. I mean, how many companies make such rails? Probably quite a few. Even the THK rails aren't stamped "THK". There seem to be no marks on either of them. It's very hard to sell a single rail with no carriages (bearings) and especially if you can't tell the buyer what brand the rail is.

I'm 99.9999% sure that my THK rail is truly a THK, else the carriages (bearings) wouldn't fit so perfectly. And since those bearings are marked THK SR30W1SS(GK) I'm pretty sure of what I have there.
But how do I determine the "Other" rail? With no marks on it and no carriages as a guide I fear all is lost. I guess I could cut it up and toss it in the trash, but I hate to ruin a 99" long and beautiful rail which is in very good shape.

Anyone selling a 99" THK rail for SR30W bearings?
Anyone want to buy an unknown 99" rail? LOL.
I am stumped, and it was my own fault...


P.S. If anyone is interested I'll try to post some pics later of the two rails and show what the "Other" rail looks like. If you think it would help identify it.
