Can you identify this?

[7HC]

It's marked 'The L.S. Starrett Co. Althol. Mass. U.S.A.'

The ball is a 180 deg. hinge, and the shaft is a snug interference fit in the block, meaning it can be rotated and slid in and out with some difficulty by hand.

My best guess is some kind of edge finder?

Thanks,

M

Looks like an attachment for a dial indicator or DTI

I have to agree aliva has the right answer for it!

Thank you both. I can't really picture how it might be used.
Can you explain further, or maybe post a link?

All you guys are not old enough. That is the attachment for a "Starrett test indicator". The rectangle end is attached to a height gage and use on a surface plate or flat surface on a machine in some cases. The rod end was attached to the holder on the side of the "test indicator which ws slipped over the body of the indicator.. They (Starrett) have made those things I'm sure since about 1945 or 50. I think they still make them. I have one in my dusty old toolbox.

Many thanks. Using that information I found a pic of it in with its full kit on eBay.

Never really been a fan of the Last Word indicators. Small range, and as Frank pointed out, not bidirectional. I have at least two of them myself.

I believe the 711's are the ones I have. My "go to" test indicator, on the machine at least, is a B&S Best Test. I like it because it does autoreverse, and I have the black face version which I can see better. I have a couple of Mitutoyo test indicators with long contacts for deep features, but rarely need them.

Starrett refers to this as No. 711FSAZ
Indicator with
universal shank and
body clamp
attachment.

Thanks, I find it amazing that they still make it, and that it's actually two separate part #s

Starrett obsoletes very little, I believe. Most of their products are well engineered, and were well made. I can't say these days. I haven't bought anything new from Starrett in the last 10 years or so. It wouldn't surprise me if some of it is made offshore, like so many other things.
