Help Identifying Sword

[McQ]

Hi All,

New member. I need your help and expertise to identify this sword. What is it? What if anything do the stampings suggest? Also, there is no pommel or drilled holes in the tang, so how would a grip have been attached?

The sword has a single edge with a very slight bow in the spine with the point moving up. It has an overall length of 46" with a blade length of 33 1/4" and a tang length of 12 1/2". It is 2" wide at tang base narrowing to 1 1/4" just before the point and 1/4" thick along the spine at tang. It has a 9 1/2" fuller on each side. The cross guard is 11" long with a 2" tall ring and a 7/8" diameter decorations at each end.

There are three distinct stampings on the blade as shown in the picture. One looks like a 'window-pane' or 'cartouche' that is 4 7/8" from blade base along spine. One is made up of two 'blobs' side by side that is 2 1/* from blade base along spine, and the last is a half-circle with a cross on top that looks identical to the Passau stamp belonging to the Stanley Family that is 7 7/8" from base of blade in the center of the blade.

Thanks in advance. Kirk
