This kit is now avaliable as a PDF download. I have kept a photographic record of it’s construction as an aid to anyone wishing to make one. I made this one up from a paper print out which I then spray glued onto thin card. I used a scapel to cut out the pieces and PVA wood glue to stick them. On some pieces like the bodies and heads some clamping was required.I also used a little silicone grease on the cams and cam bearing.
