An unusual manufacturing technique was used in making this plate. It
was struck in very heavy brass about 1/16 inch thick and the whole
tinned; then, all the tin on the obverse, except that on the crested
helmet device, was buffed away, giving the center ornament the
appearance of having been silvered. The specimen obviously was made
for a particular mounted unit, designation unknown. An interesting
detail is the letter "A" on the half-sunburst plate of the dragoon
helmet device.
