Thanks guys for the ideas. Now you've really got the gears turning in my head (meter!)My dream would be to have a display showing pumps from every decade; early curb pumps up through 70's (about the last mechanical meters).I have a restored pump for each of these decades, but not large enough trailer!I think I'll start out small with a 30's to 50's display. I'm older & retired and don't particularly like lifting heavy beasts. (I've had lower back problems all my life, but the problems started when I got into this hobby 35 years ago). Surely couldn't have anything to do with it, could it?) Sam
