Beautiful bows. Thanks for sharing pictures

Larry Hatfield has said that was the best glass he ever worked with...3M rather quickly decided it was not worth marketing the small quantities that Archery industry used...My 1962 Kodiak Magnum has that same glass with zero stress lines

3M called the glass Scotchply

Hi:

Very nice bows...I have some information on when they were made.

Your Hunter is a 1963 and your Hi-Speed is actually a 1961.

The third letter suffix after HH or HS is what designates the year it was built between 1961 and 1967.

The designators from 1961 to 1967 are 7, V, X, S, T  and A.

This is true for all models of Howatt's.
