Hello Jan,
I am about to announce a post-war DH9A decal set, together with etched wheels and a few other etched parts. There is a problem with the "A" machine on the back of the Datafile, as this (along with a number of other attractively marked examples) has the raised "hump-back" rear fuselage of many late 9As. It isn't that difficult to convert the kit to this configuration, I expect, as the fuselage is basically a square box, but given the large scale it requires a lot more detail additions and changes than a 72nd or 48th scale conversion. It would also not be a simple conversion to provide in Resin - believe me, I've looked! That said, I think there will be sufficient varied markings on the set to keep most inter-war RAF fans happy (and maybe a Russian or Chinese supporter as well...).
More news soon - I await delivery of my own Ninack kit to check some details.
