20 degree pressure angle on the higher number tooth gears doesn't "look right" to me on this period model. yes I understand why they are used (gives a thicker tooth without undercutting at low tooth numbers), but I prefer the look of 14.5 degree, Obviously all your gears need to be the same PA.
Have you tried Tracey Tools in the UK, they often have gear cutters cheaply which would likely be the older industrial standard with 1" hole, unlike the Chinese sets you can buy now with 22mm bore.
Just a thought.
