Nice find, make sure it has the metal boot clamp & update if it doesn't. 359's can leak air scuffing it all up.
That's a good call @milw saw I know my 351 was killed by a leaking intake boot. You should be able to pull the top cover and peak between the cylinder and carb to see what holds the boot in place.
I don't have a picture for you UA. I got 2 or 3 359's years back seized up from intake leaks. My dealer told me to be sure to put the metal clamp on (can be a bear to install I've read). I think it was Brad that installed an update boot kit on a 350 with the metal clamp so hopefully you can find that on the tube, should be the same procedure for the 59.
