Thank you for the information. Any clue as to why it doesn’t come up in a search with that number as that particular tool?It's a calking (sp?) chisel for sealing cast iron drain vent stack pipe with jute/sisal and lead.
I appreciate the helpWell let's see, I last saw a drain pipe caulked with lead and oakum sometime before 1974. Will go poking through the Sears catalog CD, see what I find.
Used to be putting a 9 in front of your parts # would make it pop up in Google, but that didn't work today.
More later, but the lead packing makes most sense to me, in case that wasn't obvious.
This is a gasket scraper, and there is little likelihood that OP’s “chisel” is or was ever a gasket scraper.Could handle have been cut off? Apparently same part number. Business end looks similar.

Yeah I didn't notice shape in OP's pics I thought it was flat.This is a gasket scraper, and there is little likelihood that OP’s “chisel” is or was ever a gasket scraper.
Some manufacturers reuse old product model numbers for items that have been discontinued for a while, with Starrett being an example.
A “chisel” for tamping in lead and oakum packing material for waste pipe joints would be concave down the length, to fit the rounded opening between the wider bell on the ond of waste pipes, and the waste pipe being inserted and sealed.
This type of tool would have been a standard plumbing tool any supply store carrying plumbing tools would have wanted to offer.
Philadelphia and New York City both required cast iron waste pipes for commercial buildings, at least up until recently, and cast iron was the standard for quality if you go back a few decades.
That was my first thought, but if you look closely at the picture, the leading edge is blunt, not sharp like the cutting edge of a pneumatic rivet cutter.I'm not in the caulking chisel camp ,I'm more thinking a rivet buster cold chisel or something

which begs the question:43325 and 43345 right hand and left hand caulking irons.
depends whether metric or SAE caulk.which begs the question:
were they also available in metric sizes, or only sae?![]()
Neither if it's guided by loving hands.------ what a bunch of animals on here. I'm offended. This thread is gone to ****.In which hand do you hold your Caulk before you drive it in?

I've seen references to G-circle begin Lectrolite.G-circle = unknown U.S. manu. ca. 1949 - 1964 (as late as 1973 on ripping chisels)
SAE or MetricNeither if it's guided by loving hands.------ what a bunch of animals on here. I'm offended. This thread is gone to ****.![]()
