I'm helping a friend with his 16-valve 1917 White touring car. The one part that is damaged is the water pump shaft, not from wear but from galvanic corrosion. It's an interesting challenge and is testing the limits of my skills but I think I can handle it. All of the early cars I've worked on used a 14.5 pressure angle on the gears and I'd say it's about 90% sure this one does to but the 20-degree pressure angle was known in 1917 and the White company clearly had their own ideas of how to do things...(the thread on that piece screwed into the front of the gear is 7/8-13). Can you tell by looking at the gear what it is? I could if I have a variety of gears to look at but I don't and none of what I have are 20-degree gears.
I should add, 20 teeth, DP8. The OD of the gear appears to be 2.88 but I will have to go back and measure that again. I measured it with my dial vernier and I really should have use a mic.
