Awl identification

[quiltedlumber]

Just picked up a tool box of leather stamps and some small tools . Does anyone recognize this or have information on this ?  There is no mfg ID on the tool and the storage case looks like the top cover is missing .

Thanks

It looks like a proportional divider leg.  Probably part of a set, or an add-on to a divider set or drafting tool set.

This a proportional divider. I have one that looks the same. It was made in the USA by Dietzgen. I purchased it in 1959 to use for transferring dimensions from engineering parts drawings to exploded view isometric drawings. In those days IBM computers were very large mechanical machines that required parts catalogs for identifying replacement parts.  I worked at IBM for several years, drawing the exploded view drawings of the components for creating and printing the catalogs.  

I now use the divider to proportionally measure and change the size of leather patterns. Was very useful then and is still very useful today.

Would have never guessed , just made an assumption it was one hell an awl with the diamond shaped ends . So glad you were able to set me straight , thanks for the quick response.

Look forward for the chance to use this for its intended purpose 

Thanks
