Help me ID triple triangle frame.

Recently picked up a triple triangle frame and fork that had been stripped of markings and I'm trying to ID it. Sorry no pics till next month at the earliest since I don't own a camera (wife is visiting family out of state).

What I know.
Serial # FF64199 on the bottom bracket.
Ishiwata 6 C stamped on steerer tube which is seamed.
27.0 seatpost fits snugly and the seatpost tubing appears to be seamed also.
It has the adjustment screws in the rear dropouts.
Dropouts look just like the ones on an 88 Prelude with no markings that I can find.
Brazed on tubular cable guides on the bottom of the BB.
126mm rear spacing.
Two water bottle mounts.

Thanks for any help.

I think after much googling and looking at pictures that it's a Nashbar Alpha 5000. I found an old thread with some pictures on here and a lot of the details match up. Now I need to put it together.

Yes, the serial number is consistent with Maruishi manufactured Nashbar product, with the frame dating to June 1986.

Thanks T-Mar and not just for this, information that you have posted in reference to other bikes has been helpful even prior to me signing up for the forum.

I did some more looking and there is a possibility of it being a Toure LP also. I will see whether it takes 27" or 700c when I go to put it together.

Any ideas on what tubing set it might be?

It's most likely a Road LP (Ferrari Red, 700C wheels) or Toure LP (Cool Blue, 27" wheels). There was also a triple triangle City LP but I assume you would have mentioned the cantilever mounts, if it had them. An Alpha 5000 would be a 1987 model and a June 1986 build is slightly early for a 1987 model, so I think there's a higher probability of one of the LP variants. Still, the frames appear identical for 1986 and 1987, with the big difference being the use of the new indexed SunTour derailleurs on the 1987 Alpha models.

Regarding tubing, Nashbar was vague, stating only "Ishiwata CrMo triple butted throughout". However, this description, in conjunction with the seamed construction and a 27.0mm seat post, point to Ishiwata EX-T, which was basically a seamed, less expensive version of 024. BTW, Nashbar's terminology for the triple triangle design was "tri-lateral".

There was remnants of red paint in the seat tube, bottom bracket and on the steerer tube. So it is sounding like it might be the Road LP.

Thanks again T-Mar.

Here's a pic of an Alpha City 5000 for sale on CL here right now. Looks like it might have 26" wheels in addition to the canti brakes.
