i have an old in medium shape 192, and have couple of questions about it. first according to what i have found thus far the slitter is poor shape, what was its intended use? i am new at his folks so bear with me. its steve C's fault the handles has the full curvy horns not the version with no horns on the handle, any way of telling its approx age ? it also has a added stamp for the 9 as though in the pattern it was one of the first to be switched from 180 to a 190..i used to work in foundry and so i know about changing patterns for castings so any info you guys can give me would be appreciated and if the slitter is necessary where could i get a better one? well thats it folks for now and thanks for nay help you can muster.
