Very scarce item indeed.

To answer your question, it all depends on the condition of the bore.

If you are able, it would be worth removing the big nut.

Fingers crossed, the piston won't be seized, in which case, remove it and examine the bores.

Rebuilding the intensifier (if the bores aren't scored) is straightforward, but you will need to source seals to fit.

I have a couple of these which have suffered internal corrosion.

Some firms offer a sleeving service, I haven't found one in the UK but maybe somebody can recommend one.

A perfect NOS unit (bores and seals definitely A1) would command strong money on EBay, I wouldn't be surprised at £250 as a low end estimate.

Hope you are lucky here.

I have a NOS one still in the wax paper and box. As I recall they were not giving them away when I bought it. Steve (CTR)
