Coleman Gas Smoker Grill (Model 5475-701)

 Hello -

My father bought this Coleman Gas Smoker Grill (model 5475-701) many years ago at a rummage sale.  When he bought it, the seller said that it had been used maybe 5 times.  Furthermore, my father never used it and it sat another 20+ years in the garage.  Recently, my dad gave it to me to do whatever I want to with it.

Anyway, I was going to use this grill as my first smoker, so I tried looking up information on the internet.  To my surprise, I wasn't able to find hardly any information about this product, so the thought crossed my mind that maybe this was a rare grill and could be considered a collectible.  Furthermore, it's in fantastic shape and works perfectly.  

To any and all who read this, I'm just trying to figure out how much this grill might be worth.  If it's not worth much, I'll just use it, but if it's worth anything of value, maybe I'll save it as a collectible.  

I've attached a photo of the owner's manual to give you and idea of what the grill/smoker looks like.  Mine is in near perfect condition.
