wow! and I really mean WOW! that is unreal. I'm with
@MrHoss, if you don't have an 18, put it together and use it. my first weber was an 18 budlight ots that I modded into a faux mt(lid therm, ash bucket and slide aside lid holder). you'd be surprised how capable these "little" cookers are if you give them a fair shake. if you do already have and use an 18, then do as you will.
as for the handles. if you plan to keep the grill or just its handles for any reason, coat those suckers in a clear varnish/sealant/shellac so you don't discolor the wood. if you plan to sell or part it out, vacuum seal the handles in an air/moisture proof container to prevent discoloration or damage and you'll be able to off load them easier.
all that being said, if you don't plan to keep it, please offer it up in the member sales section here so folks that will treat it right and really appreciate it will have first crack at it. to my recollection, I've not used the descriptive phrase "a true gem" to describe any cooker I've seen(via the net or in real life). I'll use it now, the grill you picked up is a true gem. from what you've posted it is absolutely flawless and as perfect as the day it came off the production line over 20 years ago.
regardless of what you choose to do, thank you for sharing the pics. I actually said "holy shit" out loud as I looked at them.
