The Kepp platinum still held 136.383 liters; where boiler and syphon was £ 598.50 was taken at the USD was taken at a Silver Rate of 45.77 (USD$ 3,138.) ; at the Paper rate 54 pence, $2,660. This assumes Troy weight (495 ozt) but excludes any additional tariff, shipping & handling cost to New York.
