The metal case is marked on the top"D. Brunton Patent Sept. Ainsworth Sole Manufacturers Denver, Colo. The item has something to do with surveying.
Sorry but I have limited knowledge about this item. The pocket transit has an old worn leather case that it fits in so that it can be attached to a leather belt. The leather case has been used and shows surface wear. The leather case is missing a metal buckle or some type of fastener for the strap to hold the top of the case shut. The metal case is tarnished from age and use.
The inside mirror is not broken and the needle moves to the right directions. The only problems I see would be that the metal case needs to be properly cleaned and two screws on the back I believe it could be used as a working piece of equipment or it could simply make a conversation piece on a desk or as part of an antique tool display.

I am a sixth grader and my history teacher gave this M2 pocket transit compass to me to research for a class presentation. I found your website when I searched on the internet. It has good information. Would you be able to tell me when it was made and possibly what it was used for by the serial number ?
I look forward to reading your reply. Thank you, Andrew. Andrew, Thanks for your email and inquiry. The M2 pocket transits were a special type of transit manufactured for the US military starting in WWII, specifically for use by artillery units. Since field artillerists need to be especially precise when aiming their artillery guns it was felt that the standard compass with a degree circle was not precise enough.
Unfortunately there is no database of serial numbers for M2 compasses. They were made by several different manufacturers from WWII onwards. I have an original Ainsworth sold to me by a retired paleontology professor in It belonged to her late husband, a structural geologist and remains a treasured possession of mine.
The serial number indicates it was made in It was supposed to come with an indexing screw that replaced and protruded from the base plate of the Brunton. They worked well with traverse boards for reconnaissance mapping in areas without topography maps or with aerial photo mosaics to located points and map structural data. Kottlowski, former New Mexico State Geologist.
Bob, thanks for the comment. I have not seen one on eBay in years. I ran across this particular transit, do you know anything about this. He goes into many practical applications of the Brunton Pocket Transit plus a very nice chapter on using a Plane Table and Alidade for topographic mapping and geologic mapping. The Gurley is much better suited to light surveying and plane-table mapping than the Brunton even with the Alidade Protractor base plate.
It the Gurley was, however, used extensively in early oil and gas exploration mapping along with the typical topography mapping tools and the Brunton Pocket Transit. This is another interesting, hands-on book. Hello Andrew, I am aware of at least three different manufacturers of the M2 military compass during WW2. There may be others, but those are the ones that I am familiar with as actually having manufactured the M2 under US Government contract. They will typically have the data plate affixed to the cover by rivets and have the initials of one of the government ordnance inspectors.
Still have my Boy Scout Silva from my time with Troop My only Brunton is serial numbered at I have owned this for the better part of 25 yrs. I am presuming it to be of Vietnam war era production. Allen, sorry for the delayed response.

Do you have a blow-up diagram that could help me fix it or know where I might send it for repair? Any thoughts would be appreciated! They actually repaired a pocket transit for me several years back. I recommend you contact them directly.
You can view the manual at this link:. I tried Brunton and they sent it back to me. I need a alidade protractor to buy. If anybody know , please , contact me on apopenha gmail. Aguinaldo, if you are talking about the clear plastic alidades made by Ainsworth and Brunton for use with the pocket transit, good luck in your search.
