My preference - WW2 RNZAF & Pacific Theatre, Allied & Axis, ETO, Mediterranean, AFV & figures
I enjoy doing research
Update In Stash:
Lots of 1/35 Armor mainly WWII German and a few Modern British/American pieces, 1/32 Aircraft and 1/48 Aircraft. Aircraft chosen to replicate RNZAF and RAAF types through the years. Some RAF & USAF types exist also.
