Welcome to the Family Kane!
Look forward to seeing you 30 year old project, I think you have most of us beat on the "I will get it finished....." time clock for projects
Does the wood have any finish on it at all?
If not, a good cleanings and some light sanding should set you up for any finish you like.
Oh yeah, let's see some pics of the old C-man tools, the old ones were usually fairly good, to real good!
