Fellow Tool Collectors,
I've recently discovered a clue and a new mystery concerning the cruciform slot Cheney Nailers -- thanks to the discovery of a box-fresh mint No. 3 Plain Face 1 lb. 12 oz. Cheney Nailer.
Apparently it is the Nos. 2, 3, 4, 5, and 7 that have the cruciform rather than flat-top 'T' shaped nail holding slot.
Still no clue as to the purpose of this variation -- except for the suggestion that it was to accommodate rose head nails.
Here's where it gets weird. These models, the Nos. 2, 3, 4, 5, and 7 are all listed in the 1904 catalog. They appear to be identical with the exception of the nail holding feature. The same is true for the Nos. 37 and 38 Bell Face Adz-Eye hammers. However, then those hammers were offered with the nail holding feature they were given new 900-series model numbers -- 937 and 938, respectively. In fact, all of the other Cheney Nailer models have 900-series numbers -- 944, 958, and 981. So why didn't they change the model numbers on the cruciform slotted nailers?
Meanwhile, I've added lots of new pictures to the site. Please check it out:
