Looking at the brass one's could they be small drawer or cabinet handles

Spot On Colin👍👍

A very strong contender I would have thought, Colin. Well done for thinking of ship's wheels.

Could be these handle grips on ships wheel. Pictures from Tajin.
Cheers Colin.

I have never seen brass thole pins, only ever wood. I have no idea what the brass things are, but would have thought that if they were intended as thole pins, the bit that would go into the gunwhale would not give sufficient support for the pressure of an oar being pulled against the upper part and would jump out. Could they be a form of belaying pin? if indeed they are a nautical item. Wooden thole pins go through the gunwhale and there is usually as much thole pin below the gunwhale as there is above. I remember some barge's boats using thole pins. I found on the few occasions I have used thole pins that it felt completely different from using rowlocks.

These are thole pins. A wooden pin is 😀fixed in the gunwale of a rowing boat to which, by means of a grommet, an oar is held when it is being pulled. A more usual method is to use two thole pins close together, with the oar between them. They are a substitute for a crutch or a rowlock.

Tajin, they look like miniature modelling tools.
Interesting ends .
The handles look like belaying pins or miniature pub beer pump handles.
Where did you get them from.
Cheers Colin.

I think that thay are solid brass
