Back after another delay due to work and home commitments.
OK when I made the funnel I also made the towing hook and towing beam.
The three parts to the hook can be seen in the first picture, strange how bad the filing looks when you take photos of an item. The "u" piece is one of those 7mm brass shackles you can get from Redbanks Models. I can not remember how long the flat piece is but it is 3mm thick, the hook part is a piece of brass rod bent and attacked with a file.
The second picture shows the hook mounted on the beam, the beam is 8mm square wood superglued together. The old shackle part is soldered to the back plate, which has two dress making pins through it and superglued into the wood. The hook support hoop is 1.6mm s/s welding rod, again superglued into the wood. There was a touch more cleaning to be done to the hook in that picture.
In the third picture the two support legs can be seen, these are pieces of brazing rod superglued into the wood. The holes they go into in the deck have blocks of 10mm square wood glued underneath to stop the tow beam wobbling
