Coyote custome bows ?

[Pryor]

My friend just got a long bow as payment on a painting job.  It is marked "Coyote custom bows by Gordon Rule".  69", 57# at 28"

Not sure if this is good thread for this forum.
I posted this on pow wow but did not get any responses.  I am trying to find a value on the bow, and if any one has any experience with these.
