Thank you for further commenting on this type of 'geringonças'. The seller also had a device for stretching gold wire, but it was incomplete and not so appealing as this one. His atempt on the wood used would be oak or cork oak.
I am trying to know further details trough the local owner of a gold museu; things like how the gold beating operation is called over here, the name of the machine, possible age and so; so far no resuilt.
