Beautiful Red Master-Touch! Some awesome memories attached to that one I'm sure!
If you are missing the thermometer that sits under the lid handle, new replacements are avail from Weber and are pretty reasonably priced. Part number is #62538
I might also have an extra used one kicking around at home that you can have for cost of postage, but it might actually be cheaper just ordering direct from Weber due to shipping rates these days...
Either way welcome to the site from Vancouver Canada!
