This is a rare New York pewter "Bud" baluster pint measure with the sealers mark A. Initially this was thought to stand for Amsterdam, an early name for New York, but is now thought to stand for assize. Bud balusters sealed A are now thought to be made in America. Top diameter 3 1/8", bottom diameter 3 1/8", height to rim 5 1/4". Let me know if you require additional information or pictures.
