A ... ? ?..... of old tools

My brother has a love of old things. This half barrel of old tools sits next to the fireplace. Any suggestions for a collective noun?
A tool box of tools is a bit tame.
Here are a few possible starters:-
A trumpet of tools?
A tidy of tools?
A tirade of tools?
A triumph of tools?
If it is to start with other than a "t", it could be a grip of tools.
