What is it?

I've been collecting unusual objects for quite a while, and several years ago I started posting them on this site as puzzles for visitors to figure out what they are. Most of the items are mine but a few belong to others, if you aren't interested in tools there are plenty of other type objects that have also been posted.

For first time visitors I recommend this archive for a wide variety of some of my best pieces.

Set 176

1019. 2-3/16" long:

The outer two are imprinted with a 4 on the large end and a 3 on the other, while the middle one is marked with a 1 (small end) and a 2.



The ends can be unscrewed and/or pulled out of the cylinders, five pieces total for each.



All of the threads have two slots and all three cylinders have a different inside dimension. I've shown these to a lot of people, so far no one has been able to identify them.











1020. 6" diameter, made around 1800:















1021. 12" long, patented in 1876:







From Ron White's collection











1022. 16-1/2" long:

From Jim Brown's collection











1023. 1-1/4" diameter, thanks to Bill for submitting this one, more guesses at Neatorama:

Patented in 1899











1024. 15" long, text on this device reads "The Leeds and Northrup Co., Scientific Instruments, Philadelphia":
