I'd missed seeing the finished effort. Nice work.
May be worth sending a PM to Lost Cosmonaut for some tips. Would certainly come out better with his resin printer. That's not to do your efforts down, but the resin ones can print a lot finer and give better results. I have Alistair's earlier ABS efforts and the difference in quality between the Miles 52 from then and his newer resin one is like comparing Mach Two kits with 1990s vintage CMK.
