I have this old hydraulic backstay tensioner (approx. 1980) but I have no
idea of what it is. Apparently it is not one of the more common brands.
Do you have any suggestion?

What is your question?

Are you trying to figure out how to put it back together?
How much it's worth?
Where to get parts?
How to use it?


If you are trying to get it repaired, my suggestion would be to look in the
phone book under "Hydraulic Equipment, Repairing". Find a shop, take all
the pieces down to them and see what they say.
