The India made ones on offer from IMA & Atlanta Cutlry will not fit a P53. They were designed for the Martini with a thinner cleaning rod IIRC.
An original will set you back $250 +/-. Do a search on this site. There was a thread detailing different musket tools. I may even have started it but don't recall. It's well worth doing the research to get the right tool.
Most of the modern repro musket tools are junk, really bad junk.
