Antique 6 Inch Bone and Silver Ruler with Caliper stoneware funnel Late 19 or very early

Late 19 or very early 20th century I believe

There are just few bristles missing (one hole's worth)

but I might do with this one

sometime between the 20s and early 50s

Antique 6 Inch Bone and Silver Ruler with Caliper stoneware funnel Late 19 or very earlyStanley and a few other tool makers produced beautiful bone rulers, which bear their marks, but I've looked and looked and not found another like this one. There are no readable measures on the bone, but on the both sides of the silver end on are marks for 4 and 5 inches, and then the caliper pulls out to measure 2 inches, with each inch divided into 32nds on the flip side. Probably more of a beautiful thing than a super useful tool these days, but
