~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Ah Yes! No.99 was an inside caliper. Contrary to some peoples thinking it was not a compass. Those are used to draw circles/arcs. The calipers are for measuring inside and outside measurements. With the inside and outside type of caliper you compare the inside distance gauged by the instrument to the scale on a ruler and read off the diameter. Simple. However, it is not a drawing instrument or dividers. The latter are used for scaling distances on a map or chart.
In fact this pair of inside calipers were originally purchased by my grandfather when he was working as a ships engineer in the early 1930s. It was part of a set of measuring instruments and I still have the complete set today with the wooden box they were sold in. They are one of my favourite tools. They are as accurate today as they were when bought. The design is sound. Sadly this economical design had now been discontinued in favour of the Veriner and more sophisticated digital calipers, but the company that made them are still going strong. The new design, the vernier calipers, can be seen here...
http://www.moore-and-wright.com/products/categories/7 - A vernier caliper does the same inside and outside measurements but carries a scale on it so you can read-off the measurement directly.
Well, there were quite a few correct - the roll of honour is...

Paula Cook-Farkas - Ummmm, this looks like some type of torture device. Either that or it's a nutcracker...or maybe it's one in the same. Net says:-->> This would be the most interesting and fiddly nutcracker I have ever seen! LOL> Sadly no! a "Doohicky Award!" Yahoooooo!
Shanne - they're measuring callipers - used for technical drawings amongst other things. Net says:-->> Ah ha! Actually no! LOL. They are an instrument for measuring sizes of actual objects. They are not effective as a drawing instrument - I think you are thinking of dividers which do not do inside and outside measurements. However, correct on the caliper part!
Alison Bailey - Yeah, those calliper things, I remember when they always put them in those tin boxes full of geometry instruments and nobody ever used them. They got taken out of the tin and put into that drawer in the sideboard that was chock full of other useful stuff that nobody ever used. Net says:-->> I think you refer to dividers that are something quite different. Tee hee! I like to sneak in shots of difficult to identify things!
Sue Wilde - Calliper. Used for measuring internal measurements...you can tell that because the little endy bits are turned out. If you use callipers for external measurements then the endy bits are turned in. Net says:-->> Yahooooooo!!!!!

I would use this if I needed to measure important things such as the width of my feet, the size of my toothbrush head, the length of my nose. Specifically spring calipers would measure all that and more. Oh well I see now it is internal, so I use it to measure the inside space between my toes and my ear canal. so internal spring calipers. Net says:-->> You would need a very big and odd shaped caliper to measure the distance from the space between your toes all the way up to you ear canal! LOL>>> ROFL... Grin!!! a "Doohicky Award!" Yahoooo!
Thanks for the fun and for dropping by. See the next picture before you go to bed tonight!
