The Cougar was a limited or special run. Most were finished quite well with fancy walnut and in white metal. They also have a Cougar madallion imbedded in the stock. These are pretty little rifles second only to the Sencas. IMHO. When you decide to sell it, you will get some attention. I have an old catalog that lists the specs but could not put my finger on it. These have come up in GunBroker from time to time. My book lists $170.00 to $360.00 but there might be folks out there looking for one to complete a collection. Most were .50's but there were some .45's. Basically it's the SS version of the TC Hawken model. Hope this helps and good luck. There are a few members here that own them. Do a search in the forum for additinal info.
Oh, by the way, I'm interested ....
Be Safe !!!
