G'day Gaz
Good to see you back mate. Don't worry about your WW1 interests fluctuating, our bit of the hobby has always been a bit of a hobby rollercoaster. Ups and downs define WW1 modelling!
I wouldn't stress the Wingnut Wings thing too much. Very sad to see them close but there are countless thousands of pristine, unmade kits in circulation and once the "these are more valuable than toilet paper" hoarders lose interest and move on, those hoarded WnW kits will filter on to the market at more reasonable prices.
I expect people will still be building Wingnut kits for some years to come. It's still quite easy to source classic Aurora WW1 kits and how many years has it been since that brand disappeared?
In the meantime Roden, Copper State, Special Hobby, Lukgraph, Eduard and others doing WW1 land war subjects like MiniArt and ICM are keeping our WW1 hobby ticking along nicely.
