Jensen Keg Board, Longboard Skateboard

I was once told this board is called a Keg Board. That they used it in Cali to ride down the board walks w/ a keg in the center and rode it down to the beach to have a party and drink. Is that true? i have no idea.

 It's a longboard and the trucks say Jesen on them. Supposedly the board is also made by the company Jesen, however, I have Never been able to find any information on this board or on the company either.

I was wondering if someone could tell me a little more about this board --- what year it's exactly from and how much it may be worth?

I bought this board off of ebay about 10 or so years ago for abotu $45.00 --- I believe it's from the 1980's but, I have no idea. The wheels that I currently have on the board are Spinner wheels (yes, they have hubcaps on them and they actually spin) --- however, I do own the original wheels/bearings that came with the board. They are orange --- I can take pics of them too if you would like.

This board has a super tight turning radius and it's very stable at high speeds (yes, i always ride this board as it's my favorite board)
