Liddle&Kaeding was a San Francisco firm that made bullet molds in the 1860's possibly continuing into the 1890's. Tom Quigley reported on characteristics of 24 such molds in The Gun Report volume 43, number 6, pages 32-38 (November 1997). The article, entitled "Loading Tools from R. Liddle & Co. and Liddle & Kaeding, S.F." contains much interesting background information about the company and details of mold markings. Briefly, the molds are seen with two distinct types of sprue cutters; one reminiscent of those seen with Remington rifle molds in which the sprue cutter is attached by two screws, and, the other, an elongated variant attached by a single screw. The two types of sprue cutters are illustrated in this image showing the elongated variant in the top 40 70 mold and the "Remington-style" sprue cutter in the lower mold marked "44". Incidentally, the 44 tool also has "HJG" stamped on the top of one handle; those initials are for Henry J. Gier, an early collector of antique loading tools and molds. Most, but not all, Liddle&Kaeding molds have "Liddle&Kaeding" marked on both handles. The 40 70 mold shown here has only the caliber marking on the side of blocks. Here is a composite image showing some details of the markings. There are links to a couple of other Liddle&Kaeding molds at the bottom of the page.

This next image shows some details from four Liddle and Kaeding molds; the two shown above and two 45 60 tools.

Here is another example of the Liddle&Kaeding mold; this one is in 45-70 and has the elongated sprue cutter. It is marked "Liddle&Kaeding" on the handles of both sides as shown. This rare 50 caliber example has somewhat deformed handles from hard use; it also has the Remington-like sprue cutter.
