Browning Safari 1 recurve age,brace height??

[Hawk2]

I bought a Browning Safari 1 recently seriel#7c2059.Anyone know when it was made? What would be the recommended brace? Also did Browning make these bows themselves or someone else do it and they just put their name on it? Thanks

Is it a 54" bow? I think Browning numbered the bows like bear at that time making your 7c2059 a 1967 bow.
