They are Starrett "last word" test indicators with attachments. They are a machinist tool used for measuring, checking concentricity and various other things. The indicators look pretty old but the cases look fairly new. You don't see this style used much anymore but some machinist still like them because they aren't affected by gravity if you have to indicate something in where the indicator might be upside down. Newer style test indicators will give you a false reading if they are upside down. These indicators are pretty common on ebay and they aren't too valuble.

Gah! Those are Starrett "Last Word" indicators! Not cheap! I think I paid two change for mine. Go over to www.mscdirect.com to find out. Previous owner must have been a machinist.

Also if you are just going to throw them out, I'll take them, I can always use another indicator in my toolbox. But if they are in good working order you could get a few bucks for them on ebay.

I used them in the tool and die shop in 1963, so they have been around a long time.

Pretty much what 71protouring said. They are also called "test indicators". The value of yours may depend on the precision level that they work at. Many indicators are marked in .001 inch increments with some at.0001 and a few at "50 millionths" or .00005 inch. What limits their usefulness is that the range of motion they can handle is pretty small. Like the 50 millionths indicator might have a range of .004 inch.

There are a few of them on ebay in different arrangements.

Starret, nice stuff! My dad has a setup almost just like that in his toolbox. Used to be a machinist.

.5 = 5 tenths

.05 = 5 hundredths
.005 = 5 thousandths
.0005 = 5 ten thousandths
.000005 = 5 hundred thousandths

50 millionths = .0000005 or .00000005?
or something like that. It's 0120 and I'm too tired to figure it out. Or is that a "convention"?

.000050 = 50 millionths.

It's always "tenths", "hundredths", "thousandths". Then in a place like I work where 4 decimal places are common, it's "ten thou" and then "millionths".

And then you get into the whole thing about what a tool reads to and what it's ACCURATE to. It may be divided into .0005" increments, but it may or may not be accurate to that.
