Guitar case wanted - Munich

hey, i'm looking for an over-used guitar case for a maffffia carnival costume...
because it should contain many guns and related stuff i need it big (so i guess a classic guitar case would make it).
because i need it for a carnival costume i don't need it to be perfect (also if it is kinda slightly broken would suit).

thanks!

ps: other ideas accepted.
pps: no, a golf-clubs case wouldn't make it.

The classic would really be a violin-case. I have one, but you can't have it! ;-)

What about an accordion case? It can fit a couple uzis for sure...

violin is too small. accordion case is too... kinda boring: i need something cool, something that everyone would say "ach-jaa, you got guns in there, eh?" (of course i'll be dressed in luca brazzi style)
