Ries,
I wonder what year that catalog was from.
I am guessing 1900-15.
I think the $500 now might be a better deal.
I have the eight or so of them in the shop AND drawers of dies.
Most of these have had no use in many years.
Ever since it became cheaper to but pipe and fittings for HVAC work
there is little use for a tool to make smoke stops or clinch lock pipes.
I still use some for decorative architectural stuff, but there is
usually no need to change the dies.
Still, I keep them. Just knowing I can duplicate most anything, using
original tooling has some advantage.
