Yep, interior is just like ours was. And yes they are heavy. When the guys that delivered our Kenmore were hauling the Maytag out to the curb, they could not believe how much heavier it was then the washer they brought in. I don't know the weight, but it must have been close to 100 pounds heavier.
As far as the lettering on the buttons goes I have no idea how to renew it. Maybe you could get a replacement button from a parts dealer. I know that when we replaced the timer which failed in the washer's 22nd year of existence, we were also able to get a new timer dial, since by this time the decals had completely worn off. Of course I am assuming that the timer, and dial are separate components.
Use her in good health. If she needs fixing, just make the repairs, and she will work for you without any problem
Good Luck,
James.
