You're on a roll, Cathy - well done!
Gloria, are they for drawing up a shutter over the windows?

Sorry Tizer it's not for that.

I think I know Gloria. I shall keep quiet for a while.....

There appear to be two of these rack mechanisms which suggests a tilting bench of some kind perhaps a circular saw or band saw?

Sorry Plaques, but no.

If I am right there is water involved....

There is water involved Stanley.

Rack and pinion sluice gate mechanisms?

I think you are right Ian.

Spot on

Where are they Gloria? was the building an old mill of some kind requiring water power?

It was in Camprodon in Northern Spain under what had been a small workshop.

I found a lot of examples like that in water bobbin mills that had been converted to private residences when I was researching water power in the Lake District for the DoE. In some cases the residents were glad I called because they hadn't any idea what the relics were.
Try this one, it might tighten the bands on you!

No offers? Clue, think old country trades.

Something to do with thatching?

Or for making sheaves of straw.

Neither of those but you are in the right area.

For making corn dollies?

Stabbing and moving hale bales

Sorry, hay bales.

Tying hay bales?

Sorry to all of you, all in the right area but not there yet. Think wood!

Is it for twisting the wire around bundles of firewood?

Sorry no. Think sheep and enclosures!
