Toolmakers Custom Depth Gages, Edge Scribe, Mini Angle Gage & Squares

Description

All of these tools came from a lot owned by Carl E. Breitkreutz, probably born around 1907. Several are signed CEB. 2 of the pieces, the ones polished circle decoration were probably from the same machinist. One is stamped "W.H.Murphy".
The heavy large block 1 1/2" x 1 3/4" x 1/2 thick comes with a rod having a scribe pin. The pin can be locked to the block with the knob on top of the block.
This could scribe parallel lines following an edge. (Sort of like what a surface gage can do with it's pins down, but this would be held off the plate. The rod is 6" long x .179 diameter. It is signed CEB and the number "20"
The small diameter rod (.079) depth gage pin is 5" and the top gage is about 2" long x .31 thick.
The W.H. Murphy depth gage has a 5" bar .175 x .143 thick, though it could have had a .187 wide bar based on the size of the slot. (How the heck did they make that slot?) It has a spring loaded slotted pull bar to clamp the bar to the block.
No idea what the little squares are. Both are signed CEB and again the number "20"
The miniature sliding angle gage is pretty neat. Again, hardened steel and circle polished. The hardware joining the slide is actually another Bar Lock, similar to the bar depth gage hardware. Does not have a spring installed, but the knob is counter-bored for a spring. Works for the gage and the knob is only a few thousands larger than the width of the gate. Fold up inside itself just like the "big boy" gages.
If you look at the small rod depth gage, you can see the very small dents from a center punch tracing the curve cut into the bar. That's an old technique to mill the radius using a pin resting on the top of the vise jaw to accurately locate the block. You can see the exact same method was used on the CEB large block to cut the curves in the block. The same small center punch marks can be seen tracing the edge.
Note: The 6" scale in the photos is not included in the sale. Sorry.
