Cylindrical 4S AA holder??

I’ve a piece of equipment that takes a 6v alkaline battery, it was supplied with a dead battery which I tore down, turns out it’s just 4xAA alkaline welded in series.

Anyone know of any sources for a cylindrical 4xAA series holder with + and - at opposite ends? I’ve tried modding the generic 4S “block” holder with wires but making decent terminals is a pain in the rear.

Any suggestions greatly appreciated!
