X2 on this. See if you can match the sizes to the following chartI’ll bite. Guessing that’s some sort of machine spindle taper cleaner like an early version of a Spin-L-mate.
Now some of you are going to need to look that up because a spin l mate is nothing like a Russian mail order bride.
Haha. Not me but yeah I imagine many won't be familiar with these. These things were expensive for what they are IMO. I was lucky to find all of mine new on ebay for much less.I’ll bite. Guessing that’s some sort of machine spindle taper cleaner like an early version of a Spin-L-mate.

Wondering if it is for lead pipe soldering. Use a torch to heat the lead and then this tool to widen the end so another section could be inserted. Just a guess.

Consider the tool you showed is Probably a Stanley #19 which was invented in 1911. Lead pipes were used by the Romans, but started to see use in the US around the 1850's. By the 1900 lead pipes were being used in many larger cities.No !
Lead is typically “annealed” at a very low temperature, and foes not need to be heated to be malleable.
For flanging lead pipe, the tool sort of looks like pic.
The tool I posted is made by Virax in France, although similar tools were used elsewhere.Consider the tool you showed is Probably a Stanley #19 which was invented in 1911.

So perhaps this was a type of tool used before the Stanley version. Still a guess.
(I just noticed it has Philips screws. So maybe newer).
