Good condition Watson helical screw condenser mount hardware - 39mm diameter push/friction-fit mount - together with two brass mounting screws. The helical screw mechanism gives both height adjustment and swing-out capabilities and is working very well.  

This component is from a 1922 (or thereabouts) brass Service model, so should fit inter-war Watson Service and similar models.  The Service first appeared in the Watson catalogue around 1919, so this is from quite an early example.  

Nice condition with smooth operation, intact paintwork and brass-work also in good order.

The item will be well wrapped and shipped by Royal Mail.

Thanks for looking.
