We sell vintage wooden propellers from WW1 and RAF clocks including the rare sector clock.  We are an authority on these two subjects and sell books on:

British WW1 Propellers
German WW1 Propellers
RAF Clocks

If you already have an RAF fusee clock please let us know the type and serial number from the back of the movement.  We are building up a database which is beginning to reveal the pattern of how these clocks were manufactured.

Our RAF clock stock includes:

Mantel Clocks.  Often referred to as RAF Sergeants' and Officers' Mess clocks.  These are usually oak but very occasionally were made in high grade mahogany.

Wall Clocks, including dial clocks used as office clocks on RAF Stations. 

Sector Clocks which were used in many RAF Ops Rooms for fighter control and are much associated with the Battle of Britain. 

Our clocks have been sympathetically overhauled and restored by expert craftsmen.

Cabinet work is carried out by Rob de Ruiter and Tom Smelt who carry out the restoration of our propellers and clock cases.

We conserve wherever we can and where restoration is necessary we do the least possible and retain as much originality as we can.

Clock movements are stripped, cleaned and overhauled by Tom.

The photos below show a stripped movement and the final assembled result.

We photograph our sector dials before restoration and do the least restoration possible. Generally we can save about three quarters of the original paint by restoring only the areas that rust on these dials, the rim and the centre.
