I'm looking for a 55-56cm celeste Bianchi frameset or complete. Let me know if you have one for sale.

Anyway this is on eBay and also on CL locally. The local ad once said it's Ishiwata but now doesn't and the eBay doesn't mention this. The eBay ad says it's a Specialissima but I doubt it and the CL ad doesn't claim it. And I can't find this model in any of the few catalogs I've found. Specialissimas seem to have chrome on the fork crown, chainstay, and sometimes more. And are Columbus tubed.

Any idea what this is? A Professional?
