Definate 40's with the upholstery on that maroon chair(which I love by the way) ,pull up carpets,look in furniture,around steps,bottom panel of that piano,........oohhhh how I wish I was there to go with you....Looks like there is alot to hunt around outside as well. How about the attic? If they are tearing itdown anyway, a few loosened floor boards wont hurt anything.....check the registers or vents if it has a heating system...back porch....You go girl!
