[modeleng] Re: Screwcutting

Eric,

Sure and what you have is a screw thread gauge for some type thread series. 
Each "blade" has a different pitch thread on it and you keep trying them 
until you find one that exactly matches whatever screw you are trying to 
make a nut for. The blades are marked as to the pitch and since you live in 
Jolly Olde England, they are probably for Whitworth threads.  Anyhoo, the 
outside of the handle will tell what they are intended for.  My gauge is for 
American threads and ranges from 2 tpi to 80 or 90 tpi.

It could possibly be a gear tooth gauge, but I seriously doubt that.
