Starrett vintage 425 Pocket 5" Caliper Inside Outside 32nd's 100th's Scale G556

Description

Note: G-556  is my inventory # only.
This was marketed as a 5" caliper.  The depth of the jaws are 1-7/16".  The outside measurement range is 0 to 3-3/4".  The inside range is 1/4" to 4".  Front scale goes to 5" in 32nd's grads.
Here is an older Starrett No. 425A Pocket Caliper.  This is steel, not stainless.  This is the first one I have ever seen with the 100th's scale on the back side.  (According to the old Starrett catalog #26, it is a model 425A if it had the 100th's scale).  This little handy 4" pocket caliper will measure inside and outside  It can lock and the thumb wheel lock works as it should.  The graduations are 32nd's on the front and 100th's on the back.  There is light pinhead pitting on it from age, more on the back then the front.  You need really good eyesight to use the 100th's scale accurately.  They don't make this model anymore, the new models made today (Starrett 1025 are stainless steel) are all in 32nd's or 64ths and retail for 7!  It works good and probably would polish up nicely if you wish to tackle that.
