Wow, sounds like you've got quite a find there!   Please do post more photos of the rest of the appliances - can we get a shot of the front panel and the tub of the dishwasher?

Based on that serial number plate, you appear to have a 1960 model dishwasher at least (the '7' is actually a 'T' - the GE date code for 1960).   I've got a '59 model GE dishwasher but the tub lid is missing - I hope you were able to save yours!  The tub gasket is a potential problem on dishwashers of this vintage, alas.  Replacement parts are next to impossible to find, but the gasket can be substituted with closed-cell foam insulation tape. 

If you need any inspiration,  have a look at what I did to my kitchen at the country house back in 2007 (link below).

Oh, and for paint touch-up, I was able to get a custom-mix made at my local Rona hardware store.  They scanned a panel from the Kitchen Centre to get the mix right, but if you need it, I kept the formula just in case.

Keep us posted!

Best bet on a paint match, is to take something smaller, like the oven door, to a paint store. They should be able to do an exact match.

Ouch!  I see why you were asking about the front grille cover...  One of these days, I'm hoping to scare up a frame and cabinet for one of these machines that I can cannibalize for the tub lid cover - when that finally happens, I'll let you know if I wind up with a spare grille!

The tub gasket will definitely need to be replaced from the look of things.  Again, try closed-cell foam insulating tape - it will probably do the job.  The only caveat is that the self-stick adhesive may not hold up for a long time under regular use; you can re-attach loosened gaskets with silicone sealant, though. 

Thanks for the tub shots and sorry for the late reply...  Moving is not my favourite hobby... LOL
