The Henry Cheney Hammer Company offered seven sizes of “Plain Riveting Hammers” from 4 oz. to 26 oz.. They also offered a 1 lb. adz-eye riveting hammer.
Below is the page from the M-WTCA reprint of the 1904 catalog.
Pictured below, from top to bottom are a No. 76 (4 oz.), No. 75 (7 oz.), and No. 71 (18 oz.).
The handle on the No. 76 is a replacement. The handles on the No. 75 and No. 71 are original.
The No. 76 and No. 75 both have the older “H. Cheney Corp.” markings. The No. 71 has the later “Cheney USA” markings.
The No. 75 is marked “J.F. Weinmann” on the opposite side of the head. Apparently it once belonged to this company, which was a milling operation in Arkansas and Missouri.
