Can you guess the manufacturer of this depth micrometer?

I suggest a depth base that fits your dial caliper. More than accurate enough for most work.

Are the not too flimsy ?I thought about getting one that would fit my Mitutoyo caliper but wasn't sure how well they get screwed on.

If I ever need to get one, this depth gage seems to be more useful for me and for what I do,the Starrett No. 237 - 6 Inch Depth Gauge it is fully manual,and I can see the numbers on the it lol:

The MIT base locks on solidly, as does the Etalon version. I have both and they work well.

I have a Mitutoyo Z readout fitted to my Bridgeport mill. I use it all the time for the reason it was designed. And then I found out I could mount a 1/8” diameter rod in the spindle and also use the Z readout as a sort of digital depth mike. In most causes it works as good or even better than a stand-alone depth mike…Dave

I have the Mitutoyo base for my calipers and it works fine. Not quite as nice as a depth mike of course, but it works.

So I looked at my Lufkin, it has 3 rods, 1 installed and 2 as in the pic. Those wrenches to not belong to the depth mic. They belong to the Lufkin bore gauge, which I have too. The wrench is much different for the depth mic. I think the 3rd rod is loaded in the mic. It appears to have a certificate attached in yellow.

They're not cheap, the least expensive Mitutoyo base I've found so far is,this one for $51.58.

There's a pre owned one on ebay for 20 US.

The Etalon 6" calipers usually come with the depth base attachment as part of a package. My Etalon dial caliper came with one.
They attach securely and work well for what they are. To calibrate depth mic rods beyond 3" requires large gage blocks or very accurate
2-4-6 blocks. A lot of trouble and expense for .001" accuracy. There are no tenth reading depth micrometers.
