This wonderful 14K gold combination pen/pencil was made by L.T. & Son.
It measures 5&1/8" long and is marked just where the barrel meets the pencil (see photo). It is marked 14K and LT. The case design is a bamboo motif.
Condition is very good with no dents or dings. Some light scratching where the cap slides on and off. No Monogram. Pencil has lead, but the pen (ballpoint) does NOT have an ink cartridge.
Dating this pen exactly has been hard. The first ballpoint was made in 1945 so this is after that date. Style-wise I feel this might fit in the 1960's.
