Shown is a US Glass Factory C (Challinor) Catalog 1892 as OMN 16011 and OMN 16012.
NOTE: Sid Lethbridge 2021 - No. 16011 was made in at least three shapes - 9" plate, 8" nappy (bowl) and a card basket. The last two are hand worked from the plate. They can be seen on page 218 of United States Glass Company Vol. 1. No. 16012 is not the same mould as No. 16011 which is why it was given a separate number.
