acrylic cases are great, but on a busy desk you will probably find that it will attract dust very quickly! No shelf or display case it can live in instead?
I have one of the originals which has been on a glass shelf in a display case with other model cars for years and now lives in another glass unit in my work room. If you can do it, glass cleans easier..
Thanks both, good points on dust and damage. Glass sounds ideal and if I can persuade local building control It'd also allow me to display some other items too
