For your consideration is a wonderful vintage miner's blasting machine -  VME 225 from the VME-Nitro Consult. Was in working order when retired from service (blaster himself retired) and has a clean battery box/holder (no battery leaks or corrosion) but assume like any of these they should be tested/inspected if you plan on using it.  No battery included.  Great for collecting and/or the best bookends you could ask for.
