There's something you don't see every day. PJ O'Hare Sight Micrometer for 1903 Springfield...nice. Never fails to amaze me what you have in your pocket.

Have one, it takes while to use correctly. One is certainly not making elevation corrections like we modern shooters do with it, as you have to do the following to make a correction:

1) at the start of the match have the tool fit to you preset adjustment, that is when you fit it over the leaf it is exactly set with no wobble.
2) if you want to make an adjustment in the match you fitrt it on the leaf:
3) the loosen the sight elevator screw .
4) then make the sight correction to the tool
5) then tighten the sight leaf screw
6) then remove the tool.

That said it does allow for precision adjustments of the analog scale .

When did 'Lucky Strike Green' go to war?
Ironic 'carrying case' for a precision shooter's rear-sight gauge.

When did 'Lucky Strike Green' go to war?

The brand’s signature dark-green pack was changed to white in 1942. In a famous advertising campaign that used the slogan “Lucky Strike Green has gone to war”, the company claimed the change was made because the copper used in the green color was needed for World War II. American Tobacco actually used chromium to produce the green ink, and copper to produce the gold-colored trim. A limited supply of each was available, and substitute materials made the package look drab.

Works better (and faster) if you leave a "slight" tension on the sights set screw. Use the micrometer to drag the sight to setting, set the screw, back micrometer off 2 clicks and remove. Quick and easy

When using the O'Hare sight mike, always make sight changes in the same direction to reduce backlash. To take off a minute of elevation, take off two and then add one.

More story to my photo, the P.J. O'Hare rear sight adjusting tool belonged to a man by the name of Vern Rose who lived in Chicago, he shot at in the Camp Perry Matches just before WW2, he also joined the
US Marines before the war. He also served in the South Pacific starting at Guadalcanal in 1942, he survived WW2 and was around for a long time.

The Lucky Strike logo is on a metal tin which reads on the side LUCKY STRIKE CUT PLUG TOBACCO and belonged to my father-in-law and is from the 1930's period, he was a WW1 veteran.

I use one of these to great effect with my M1903 Springfield rifles. They are getting expensive!!!

Good Day All,
My Grand-Uncle (Maj. Rex Z. Michael) served in WW2, Korea (Chosin) and was on the USMC shooting team where he served as 1956 3rdMarDiv. Team Captain. Years ago,before he passed, we spoke about his time on the team and he gave me this P.J. O'Hare micrometer and stated it belonged to a shooting friend who was part of the Marine contingent aboard the U.S.S. SARATOGA (CV-3) during WW2. Given my Grand Uncle's history and other interesting bits in his shooters boxes, I tend to believe the story.
Its conjecture but I posit the electro pencil engraving was applied when the ship was decommissioned as a reminder of the original owners time on the ship. In July 1946, the ship was a target for nuclear weapon tests during Operation Crossroads and sunk.
I am curious about the "U.S. 812". I recall seeing another micrometer with similar stamped numbers and only surmise it was a way of accounting for the item. Does anyone know another reason for this marking?
Regards,
Michael
