Found last week at an Estate Sale and alerted to this thread by
Lugz, here is my Hallowell No. 25 Key Kit.
Exactly like
RTM's No. 50 above, mine has "KEY" followed by the HallOwell logo and then "KIT".
It does not have a “SOCKET SCREW KEY KIT” stamp like Lugz's No. 25.
It also lacks any mention of "Celenese Plastic".
In order, my stamps are:
NO. 25
"KEY" followed by the HallOwell logo and then "KIT"
STANDARD PRESSED STEEL CO.
JENKINTOWN, PA (not PENNA.)
MADE IN U.S.A.
If there was ever any text on the last three panels, it's gone now.
Like RTM's No. 50, my No. 25 seems to have been designed without a collet. I have to wonder if this (edit:
the collet) may have been a later "improvement".
It follows, also, that the name “SOCKET SCREW KEY KIT” may have been a Marketing tweak over the Plain-Jane "Key Kit". The same could be said for the dubious worthiness of touting "Celenese Plastic". The only fly in this theoretical ointment is the State abbreviation--I would think that PENNA. would be older than PA.
I have a full compliment of the advertised bits--plus two extra.
One lacks the text of the others and has only .050 instead of the odd fractional 1/20.
The other extra has neither text nor knurling but measures out to 0.0908, which fractionally is 93/1024--a size you almost never see anymore...
Finally, it seems the little knob/pin below the pivot should be to either lock or release the pivoting feature of the tool, but mine doesn't really do anything. I can imagine it has worn down over the years and no longer engages the locking mechanism, but don't know for sure. Does this feature work for anyone else's tool?
