Hot Rods Help Identify Gauges

Can anyone help identify these gauges. I believe they were in an box of stuff I got with a '34 Ford years ago. Getting ready for a swap meet and don't want to mislead anyone.

 

Similar to GMC AD truck but not Oil pressure only went to 60 chevy only to 30 psi

 

they don't look like they are out of one of those GM trucks, though. Same overall layout, but different look.

 

51-52 Ford F series truck

funny, I googled 1950 ford truck gauges! so I didn't find those.

 

Thank you..
