An update...
The 1/72 set has been sent to the printer to ensure there's no issue with the artwork...mainly that it's set out the way he needs it to be. I need to make some minor changes to the colours - just changing the shade of blue and red on the logos and stripes. All scales have been sized to the respective models and I'm happy with the fit. Each sheet has enough decals to model both the early and late versions. I'll be doing both in 1/72. At this stage, I don't have a placement guide due to the difficulty of finding a decent 3-view to use as a starting point, but I'll keep the search up.
If youse bloke are interested, I need minimum orders to move to actual printing:
1/32 - need two orders
1/48 - need four orders....can do it with two, but it pushes the price up.
1/72 - as per 1/48.
Basically, I'm recovering the printing costs and nothing more.
