I love the floor too...
Some tiles are bad, especially the ones that were under a row of shelves. But it was so dirty when I got it a year ago, ran a Minute Man floor scrubber over it all twice and really did a great job. It's mainly for my 13 classic cars, but there is an older original building connected to it with a basement, hardwood maple floors, think grocery store 1900 style. That's where I am putting the appliances and other things for now. I still need to repaint, keeping the 50s colours of course and other things organized.
My grandparents bought that Redwood Weber grill new in the 1970s, they only used it twice, because they didn't want it to get dirty lol. That generation was great, keep things new forever. That's also their 1976 Monte Carlo they bought new, think you can see a bit of it in the snow blower photo, grandma left it to me because I always did the work to it.
