Hello,
I don't know if your talking about display case or only cabinets, but I use to put each of my model in a display case from Schucco (Germany).
I find them on
www.nimpex.de
I think you'd better speak german to contact them cos' they don't speak english (nor french BTW
)
one 1/24 case cost around 9 euros.
hope it helps
Phil
