Those belt drives remind me of the old Daf variomatic transmission. No diff needed and very good in snow.
Couldn't they go backwards as fast as they could forwards?

Someone I worked with many years ago had one. There was a lever on the floor, push it forwards & it went forward, pull it back & it went back. It went just as fast back wards as forwards, which was not very fast at all! Very slow off the line with the small engine & a centrifugal clutch. As KF said, fantastic on snowCouldn't they go backwards as fast as they could forwards?
Normally with steel tubes, as this is, you would have either GRP or Phenolic outers but for some reason this one is brass so that is the way the MCA want it to stay.Quite a lot have synthetic outer tubes now. Probably a bit yachty for you
Bit like my Austin Champ. Five gear box with a F-N-R separate lever. I believe that the reverse was slightly higher geared, so technically could be faster backwards. Since I managed over 90mph with the screen down, going forwards, the max reverse was not an area I intended to explore to the limit. Daft back then, but not THAT daft. Bought it for £45 out of a farmers field, then to the SOF and back to recover a boat. Around 9 or 10 MPG...Couldn't they go backwards as fast as they could forwards?

Phenolic is not great, it doesn't seem to last, also it swells in water so you have to have it relatively slack to allow for that.
GRP is good but not nice to machine as the dust coming off is not good to breath in and it is quite abrasive for the lathe.
Be a little careful - I wouldn't mind betting if they make stuff for people like McDonalds, there's a line in the contract/purchase orders about no pictures and no posting it for the world to see.

Looks horrendous, and is..
The top and bottom bits are the cast iron keel of a 20ft sailing boat I am fixing up. The piece on the left is the steel centre plate that lived in a slot in the centre of the keel.
It was so badly corroded, that I cut out one side of the cast keel to get the plate out. Now de-rusting it all prior to putting it back together for a May launch. Rest of the boat is so-so, except the sails are very tatty/ripped/rotten. Found some bigger others that I can recut. Won't be fancy, but bit of cheap fun round the islands here.
The pivot for the plate was a 'plastic' 32mm rod that relayed on a bit of water expansion to stay in place. Nylon?
The French website that is popular with other owners is a bit stunned at this effort. Nobody else has hads to deal with such an extreme case.

Here is the boat:https://sailboatdata.com/sailboat/kelt-620
Has a good rep, as the first smaller boat to get 'semi high seas' rating. The one in the spec is the fin keeled version, 'mine' is the shallow keel with plate. Waters about here are often a bit shallow, so a better bet. French friend bought it several years ago. He has trouble figgering which end of a hammer is the heavy one. So I relented and took it over for a half share. Plus, is that he has an oyster shack on one of the Estuarys with a free mooring.
Nearly there with my 4” exhaust project, it’s a big’un.

haha not quite. Just a large BBQ. I haven't taken many pics of it for some reason. This is a pulley/winch system to raise and lower the grille. It all sits in a brick fireplace so the ratchet mech and handle will be mounted on the outside.Shaft looks long, whole pigs? or Ox? Nice work!
