I have one close to yours.Mine has EE by the grip.#55....Mine is a transition Bear archery Deer slayer.Probabily made by a Bear archery boyer.Trained by Nels.I think they told me it was probabily made in the late 1940s.I would like to think that Nels Grumley had a hand somewhere in it but because it wasn't signed by Nels.Its not a Grumley.Mine is Osage with a light green fortesian backing.??????
