Here's an original 79th New York glengarry I examined last winter. There's no date to it, but my friends and I believe if could be one of their 2nd issue glengarries in 1864. It was made in Scotland and imported for the Highlanders return to New York City......English markings and everything.

Its a bit taller the modern ones. There also is a SLIGHT curve on the bottom edge.







Don't mind the reproduction.... Its an early model
