Looks good, I remember having those forks on mine years ago, they were the same as on the Mongoose Amplifier. The caliper mounts snapped and I eventually bought F3 Carbons. Will load some pictures shortly.
Many thanks for all the comments folks, I'm very happy with her.
The fork remains untested so far but it clears the frame by about 5 mm. I do need to rework the cables a bit to stop them rubbing.
I just had a quick look for some evidence of seat-post binder braze ons and there's not a trace.
I'll take some more pics when the sun shines; I added a Carbon Flite that looks pretty nice on it.
