I don't know much about Adirondack bats, though I continue to research and learn. I think if you could post pictures, that could help some of the other members give you an opinion and some information on the bat.
There is a mid 1950's Mathews Adirondack Game Used bat ending tonight in the Clean Sweep auction that perhaps you could compare your to:

I don't know enough about Adirondacks to make a bid or be able to determine it's authenticity as a gamer but I'm sure some others could make a comparision between the two. I'm interested to hear what others have to say so I can know what to look for in the future.
