If this is a discussion thread on the flying boat, among others, I'd like to try to discuss something that may or may not yet be extant on the internet. I'm referring to a pair of designs by RJ Mitchell for Air Ministry specification R2/33, which the Sunderland was a result of. Mitchell's contribution was under Type 232. It was a gull winged 4 engine patrol recon flying boat with 4 Goshawk engines, and instead of wing mounted floats, it was to have sponsons, ala Martin Clipper, and was to be armed with a 37mmCOW gun, 3 Lewis guns, as well as accommodations for 2 450 - 500lb or 4 100-250lb bombs, plus 4 20lb bombs on each side.
This was oultlined in Ralph Pegram's "Beyond the Spitfire, the unseen designs of RJ Mitchell.
I've tried looking in the internet to no avail, so if anyone get lucky, please share.
