Of the binoculars in your list I only have the Tasco 400 and a Bk7 FPO Rangemaster but I should receive a Cory Suddarth reconditioned Bak4 FPO CF Rangemaster within a few days, apparently this particular glass is a very good example of its type.

Thank you again for the clarity and comprehensive nature of your report.

In a 1952 ad Bushnell claim for the Rangemaster that "All air-to-glass surfaces hard coated"
