Sorry, I was wrong. The other profiles cover RN Walrus, and those serving on the Channel front and the PTO.
All I've been able to find are serial and code detail examples for 283 and 284 Squadrons, operating Walrus IIs.
283 Sqn, moving around between Maison Blanche (May 43), Tingley (May 13, 1943 to May 30, 1943), La Sebala until 28 August '43, then Ajacio, Borgo and Hal Far, the latter on 6 April '43. Walrus 1 and II, example X9498, coded 'B'.
284 Sqn. Algiers, June 1943, then moves to Hal Far,, Cassibile, Lentini East, Scanzano, Gioia del Colle, Brindisi, Alghero, Ramatuelle, Bone, the latter on 15 Sept 1944. Walrus II, example W3012, coded 'W'.
Colour schemes are thought to be the standard Temperate Scheme, with serial numbers in 8 inch black characters, and Dull Red code letters, probably 24 inches high.
Hope this helps a bit.
