Agreed, my 'not too lazy' (revised attitude
) approach is preserve it as best I can so it continues to function as it should,
and so the next owner has the option with a fighting chance to restore it perfectly,
plus you might get a better cash return on it too in the future if selling
especially if it's not a crusty sharp ended creaky rust bucket
Vintage bench vise resto Youtubes are a good looksee too btw, I picked up a few extra tips from those excellent tubers
I purchased a couple of heavyweight oldies recently (the old school type that won't break if you lean on them a bit
)
and kept it simple, got rid of the rust and generations of spider and victim carcasses
applied rust inhibitor and lubed all the parts
They work like they did 60 years ago, have that vintage 'looked after' vibe,
and if the next owner wants to go the distance and do a full resto, they won't have any drama doing so
FWIW I reckon Mr. Carlson would have to upload dozens of videos to cover some of his resto work techniques and materials/tools/chemicals/paint etc
for getting vintage electronics looking (and performing!) Day One like he does
