Default Lorch Junior lathe slide rest info?

Hi


I'm not neccesarily into watchmaking, but I found a Lorch "Junior"
watchmaker's lathe for very little money

see http://lathes.co.uk/lorch/img2.gif

I want to keep it for tiny precision work or trade it towards a larger
lathe (hopefully of equal quality - that liny lorch is gorgeous!)
which still fits my very small (hobby) workspace.

The Lorch misses a slide rest. I understand that the increase in value
of the package far exceeds the investment in a used slide, so I can go
two ways: find the original slide rest, or get another one and adapt it.

I suspect that finding the original rest is probably impossible, and I
know of a working slide rest, non-original, for sale here in Holland
which probably has enough metal on it to be made to fit my bed, but I'd
like some information about the original.

If there's anybody that has a Lorch "junior" who could provide me with
info or (gasp!) pictures I would be very grateful.

I assume the bottom of the original rest to look similar to the
Headstock; a ridge over which goes a small block with a straight side
that fits the straight side of the slot in the bed, and an angled side
that pushes the appliance to the straight side, alligning it.

But the way it looks on the picture, the bottom part of the slide rest
is way too thin to accomodate the kind of excentric lever (1) that draws
the block onto the headstock through bolt (2) and nut (3) -see ascii
drawing below.

So the main question is : How was the slide rest originally attached to
the bed? I'm not above "creative" solutions but the suggestion I got
to cut a slit in the underside of the bed to access te screw from
underneath is a little too much.

Thanks for any info (or any info about any info etc.)
