I brought my Raleigh Super Course to my LBS to get the Bottom bracket taken out, and I asked em about the fork on my frame...explained to them that it doesn't look original according to the early 70's catalogs, and there's no identifying marks on it.

They showed me the top of the steer tube and pointed out the hacksaw marks from where it had been trimmed...told me it was a late 70's - early 80's japanese steel fork.

The fork looks fine, is true and its fully chromed..so there's no real reason to replace it, but if I wanted to get something made of Alloy what would I look for?
