Referring to BY.3/G.10.11.37. the Wraith gear, standardised for Bentley 111. and intended for P.111. as well as Wraith and Bentley 111 already has an eccentric bush adjustment, and does not use the offset roller, so that it appears to be only a question of modifying the present P.111 and 25/30 gear.
