There was never any reason to make a cast aluminum fork other than to have something to advertise.
Calling it a death fork may sound extreme, but what does happen if your front fork suddenly evaporates (rhetorical question).

The bikes themselves are straight-gage tubing, comparable to Raleigh Grand Prix. They were outfitted nicely, and along with their sister line Lambert used their version of the TA crankset.
