From the Original MAUSER factory in Oberndorf:















Ok, so it is not a rifle... but as a tool maker who loves tools ALMOST as much as guns... finding a mix of the two is pretty awesome. Course, I wish I could find some actual mauser tooling that was used to build and work on Mauser rifles.

That is pretty awesome. Nice score!

Very nice find.

Sweet find.

My grandfather asked me about the 3.42 AD marking below MAUSER in the second to last picture.

Do you suppose it was made in March of 1942?

Well how cool is that Neato find!

Can any one say what use the V-notched anvil on this micrometer is specific for?

Thread mic?

Myself and a few other toolmakers have been discussing this. First appearances are that it is a thread mic.

A few problems present themselves. The point zero's into the v. Any variance in a radius will result in a different tangent point changing your zero.

Second, if I have time this afternoon I will take pictures of the anvils. They are marked M5-7,5. To me that reads M5 to M7.5, however, again, varying thread pitch would result in a varying zero. Is that a 5-7.5 pitch? Is there some form of standard that maybe is missing?

These ARE thread micrometers...

If you note the difference in set up. These have a point and a "dash" to measure the pitch. If the price for the above set was not so much I would be interested.

My guess is they are a specialty mic for a special job. Wish I knew for what!

Perhaps for measuring something like a 3-cornered or 5-cornered object? An example would be the slug from a barrel with an odd number of grooves except that the mic (I learned it as 'mike') appears to be too small for measuring bullets.

What you show in the picture and then what the directions show are not the same tool. May have been modified?

Might be the directions are generic mic adjustment instructions that apply to all of their mics.

IMO it's most certainly a thread mike.....and in the English threads are made for a range.....such as 14-20 (threads per inch)

Yea, there thread mics, the e-bay listing Fal has highlighted show the directions as such with that set!

BUT, if you look at the ebay item and the item I have pictured above, the anvils are different. The mics I have cannot be used as thread mics... or at least on any english or metric bolts I have access to.

That is what makes me wonder...

Fal, The mike you have is a 0-25mm thread mike,and a very nice one I might add. The anvils you have are for 5-7.5mm pitch, which is very coarse. They may belong to a larger mike,as I can't imagine cutting that coarse of thread on a screw less than 25mm in dia. There are probably 5 other sets of anvils for that mike. The knob is for zeroing the anvils when you change them. It should be at zero when fully closed , like any standard mike. I have a Carl Mahr 1-2 & 2-3 thread mikes. The chrome one in Ebay listing you posted looks identical to mine, maybe Carl Mahr made them for Mauser?

Nice to see someone else ate up with this stuff also!

Enjoy!
