This unidentified mark is often found stamped on ceramics or enameled metalware. It is included in my archive due to the similarity with other marks used on porcelain and ceramics, e.g. M190826 or J.B.&W. N.Y..

M190827a
"GERMANY" next to a triangle which is flanked by "N.Y." and contains "L.G.Co.". Found on a porcelain plate.

M190827b
Impressed "GERMANY" underneath a triangle which is flanked by "N.Y." and contains "L.G.Co.". Found on figural ceramic cremaer.
