[TheForge] Power hammer ID

[Dan Armstrong]

I've been helping a friend who makes butterfly sprinklers and uses an
older power hammer to make points on the 'stick in the ground' part.
    I have a 50# Little Giant and am somewhat familiar with its' working
parts but this one is different in that the spring mechanism is an
arrangement of upside down leaf springs and the clutch is steel on steel
contact something along the lines of a disc brake. Seems to work all
right though.
    The only information I have is on the side of the hammer, "The House
Hammer
                Made by The House Cold Tire Setter Co. Ltd.
                Pat Applied for Toronto (Canada)

Anybody have any knowledge or leads on this? Thanks.
