I was hoping someone might be able to assist me in gathering some information, plans, or photos of the above. I recently saw these mortars on Corregidor, and later found out that there were identical mortars at Ft. DeSoto in Florida.

When I saw them in the Philippines I was very intrigued. I enjoy building scale models of old artillery, and these guns immediately caught my attention. I'd like to build a miniature of the M1890 mortar first. I've found a few references, and I've been in contact with the armory at Watervliet, NY, but would welcome any additional suggestions from this group.

I was really pleased to hear that identical mortars were in Ft. DeSoto, because I live about 90 minutes from there. I spent last weekend taking some measurements of the gun itself along with a few of the carriage. The problem is that there's a lot of missing parts, especially on the ones here in Florida, but even the Corregidor mortars are visibly incomplete.

I took a LOT of photos of both locations, which I'd be happy to share if anyone is interested. I also put together a CAD schematic of the mortar based on the measurements I took last weekend. You can see that here: http://tesoritos.com/tx/M1890_Mortar.pdf.

What I'd really like is a very good, legible set of engineering drawings.

Thanks!

mhanson,

I would go to the CDSG book "American Seacoast Defenses" pp. 149 to 155, there are some great drawings there. I'll soon be posting a photo of the emplacement pit foundation.

Ordered it, along with a few other books (and a hat Very Happy ).

Also have a 3D printer coming, hopefully that will help me in my quest to build models of these guns.

Thanks.

Mike

Ordnance Department Document 1698 IMUC 12-inch Mortar Carriage Model 1891 (1899, 1904, 1909, 1917R) has a set of drawings, not quite at the scale you need, but better than nothing. I thought the CDSG had a scan of this document, but I see we do not. Not sure where to tell you to look for a copy.

Also Technical Manual 9-456 12-inch seacoast material 12-inch mortar mounted on mortar carriage M1896MI has some good photos of the details of maintaining and repairing the weapons, the CDSG does have a PDF copy of that manual. I can send if you contact me.
