Ages since I mucked about with wooden props but:

Diametre 1830mm , Pitch 2310mm (distance forward of one revolution of that pitch.) Drawing No 207 AC may be aircraft number but not a familiar one.

My guess would be either

1. a BA Double Eagle (one of these was built with Gypsy VI’s) built 1936

2. A Swallow II modified to sport a Gypsy VI.

Nothing else really fits the Drawing Number.
