They look like my old Forks that i sold to Dan Harris at MK a few years back..
that stem is the wrong stem for the forks as the forks are the early ones & its a later stem.
the guy i bought them off kept the early type stem as it was a fair bit chunkier
the chrome still looks good, it was a massively thick plating job, i reckon you would have had to grind out the lower race to get it on there
