Compression on 5000 gas

I am looking at an older Ford 5000 ( pre '67) gas burner. Want to do a compression test. What numbers would be good/acceptable, dry and wet?
 
The big Ford manual says 115-150 with max 25 psi variation between cylinders.
Says all plugs out, throttle open, 200
rpm cranking speed.
These would be dry numbers.
The wet/dry test would only be used to determine if a low number was caused by rings or valves and not for determining overall condition of top end.
Good luck on getting it.
