Thanks Greg - it feels like knife edge stuff to be honest - like every next sub-build is a bit of a puzzle. The resin parts are nice enough to build and adapt, but very fiddly, and fitting them requires a bit of creative thinking (it is certainly testing me!).
I'd guess that the Hasegawa kits previously available must be more straightforward than the`Nichimo version. To be honest I am a little surprised that there is not a more modern version in 1/72 or 1/48. There were around 1500 made. It was a versatile aircraft being used for recon., and rescue; capable of dropping a bomb on shipping, and even used in kamikaze missions as the war drew to a close. It was used off tenders in China; off cruisers; and of course had a role at Pearl Harbour; in the Coral Sea and at Midway. So scope for a lot of builds! Definitely worth a bit of research and with the anniversaries around now certainly worth getting out of your stash!
