Longbow Information:

[Niyanan]

I am looking for some information on a longbow that I purchased new in 1980 in Calgary. It is a laminate construction and is hand made. The maker has inscibed the bow with the name "NIYANAN" it is also inscribed with "No. 4 1980 58 @ 28" ". If anyone has any information on who made this Bow or what "NIYANAN" means I would appreciate any information.
Thanks
