I have 1950 AC Tractor Mod. # WD45
The replacement oil guage goes from 0 to 30 psi
My oil pressure is over 30 psi and hangs up needle
every time. I need a guage the same size as the original,that screws directly into the oil filter base that reads 0 to 60 psi. The original guage didn"t have any numbers just the word NORMAL
any help appreciated.

I never owned an old AC that ever read over 30psi. Is it possible you got a defect gauge?

I agree with Max, I didn't think the system could develope that much pressure. Most people complain about the extreme low pressure on these tractors. I have a WD where the needle reads on the "R" in normal when hot but I also have a WD-45 where the needle barely leaves the peg when hot. I'd stick that 0-30 gauge on my air compressor with the regulator turned down real low and compare it with the gauge on the compressor at different settings.

Normal oil pressure is 12 lbs. Yes, check for a defective gauge first. Next, check that the pressure relief valve is not stuck. There is a plug on the right side of the engine near the dipstick. Take it out, then the spring, then the relief plunger. For adjustment, add washers between spring and plug to increase pressure, add gaskets to the plug to decrease pressure.

Sandy Lake Implement in PA has them and will ship you what you need - great folks to deal with. I bought an air cleaner cap for my 1950 B (it looks identical to the original but is painted black, which you can chage easily enough!) for 22.50 and an oil gauge (with Allis Chalmers and "normal" printed on it just like the original) for $27.96.

If they don't have the dipstick try Roger Van Camp in Indiana - He has lots of B and C parts.
