Sounds like an early 70's Super K. Is the Bear emblem on the side of the riser flush with the bow or rounded and above the flat surface of the riser?Does the bow have a stabilizer bushing in the front?Are there three patent numbers on the lower limb and Canada 1953 or one U.S. patent number?
In general,flat coin,no stabilizer bushing,3 patent numbers,most likely 1970.
Same as above but with stabilizer bushing,most likely 1971.
Raised medallion,one U.S. patent number on lower limb,still brown and grey wood and no red accent stripe through riser,most likely 1972.
After that,I am not positive on year without looking in the catalogs as I've never owned a Super K that was made after 1971.Hope this helps.
