This has just surfaced on Flea-bay; a complete WS A78 duplex rabbet plane

This is the precurser to the Woden W78 and the Record 778, both of which are vastly superior to the Stanley 78 which spawned all three.

It is complete and the seller is only asking $75 for it; that seems a pretty good bargain to me. No link to the seller; it just came up in a search and I know rabbet planes come up in discussions every now and again.
