So I go to my Project Manager who has been with the company 40 years...his only job ever has been with this company and tell him about my find by the shop. He in turn says to me, I have an old weber in my garage, but now I use a propane grill a coupe of times a year...
I did tell him the vent tells all and sends me this picture of the vent and nothing else. He has had it so long he cant remember what occasion it was bought for him.
Yes, the one by the shop is 23 years old, bought in 1990ish to burn the typical burger, and maybe get fancy and have a bratwurst bath of onions.
I will post the pic of it from the iphone.
My guess is that it is been idle for 4-5 years since the economy went south....
