Hi John,
I started out with Cubs, as they were what I could afford. All the ones I have are nice shooting bows. It is interesting to follow the shapes from early to later bows. From the top down:
1957 Kodiak 54#
196? Cub 30#
1959 Alaskan 44#
1955 Cub (2 of them actually, 60# & 54#)
1956 Cub 42#
1954 Polar 51#
1953? Cub #35
The second one down from the top has glass similar to yours.
There is a lot of knowledge here, much more than I'll ever have. The best way to find out stuff is to post pictures and ask questions.
Have fun collecting. It is habit forming. Enjoy shooting what you have. Learn to make your own strings.
