Old School Hero
In trying to pin point stuff by exclution Im pretty much convinced this should be a Blizzard. This actually supported by a small detail that I thoughed of yesterday evening. This frame has an ovalisation on its seattube, near the BB. This distinctive feature is what one finds on Tange tube sets. The Avalanche was completely constructed out of 'plain' 4130 CrMo, whereas the Blizzard had Tange tubes in the front traingle and 'plain' 4130 CrMo for the stays....
I hate to complicate things for you here, but I too have the seat tube that ovalises as it enters the BB.
The 'grades' of cro-mo that went into the builds were all Tange's: Prestige for the Blizz, 'MTB' for the Ava. and Hammer, Infinity for the Fusion.
For fun, I checked the Toyo site, they have made bikes for a few favourites on this site. I wish I could read Japanese.
Oh well, I like looking at pics of bikes being constructed. Boy, I really wish I had those skillz.
