Picked Friday evening. Appreciate any assistance in providing correct id.

Dimensions? Overall length, width just below driving band? What is inked on side? What is the complete stamping in driving band?

 

Looks like maybe a 3" or 75mm, but hard to tell...

The date 1903 sticks out, the US had in service a 3" field gun of that time. That said, as Pzgr stated, my first guess is a 3", as it was a common US artillery round prior to WW1. During WW1, the French 75mm was the most common allied field gun. I am certain the group at the BOCN website could have it positively ID'd in a minute. A very nice piece by the way, not " common". With your permission, I am willing to post it on the BOCN website with the critical information that Pzgr requested...and weight....about 15 lbs I suspect?

If it is 3" and I had to guess, I would say its a projectile for the 3" 15 Pounder M1903 Seacoast gun...if it is, its a pretty scarce projectile, for an even scarcer case...

 

I have an AA round for the 3" 15 pounder I lucked into, separately...very rare complete rounds...

Thanks for the feedback. Weight 14 pounds 6 ounces. Overall length 11.5 inches. 3". Ink and band both state "Target Practice". When doing some on line research I did bump into one citation that indicated the initials "D.G.S. & A. Co." were coast artillery related but when looking at article it failed to show up as a complete abbreviation (will revisit). welcome to share posting with other sites.

Does the threaded hole on the butt open up more into the shell ( TP rounds of that type wer filled with sand) or is it just threaded to accept a screw in tracer? The BOCN folks are still unable to give a positive ID, but have much info on the company....I have a period Naval diagram of what it may be, but file is to big to load, ( again) or so the message says.

Base has threaded hole of about 1.25" in length and then opens up into a large empty cavity. Appreciate you sharing this with the folks on the BOCN. I'm going to check out their site and info. Nice to find an item that provides a little bit of a puzzle.

Found interesting history on the short lived Driggs-Seabury Guns & Ammunition Co. of Derby Ct. Appears to have been in business 1898-1903 when Seabury passed away and they underwent a series of location, management, affiliation & ownership changes. Interesting is their venture into the motorized vehicle market in 1913. Company closed in 1925

 

Thanks 917601 for all your hard work.

I finally got this image to post. I found it on the NavWeapons website. Identified as a 3"/23 TP round. For some reason the entire chart did not go through, see Fig 4, yours? I suspect so, it says the interior was filled with sand. Now it is up to you to research what type of artillery pieces they were used in. BOCN experts are still commenting, they have all sorts of the Company information, but no positive ID yet.
