I'll get you the part numbers tonight. I get them from an alt shop. The units are passenger type that are rewound for 48v. If I have enough water I can get 45 to 50 amps out of one of the units (wired delta) the (wye) units will get up to 40 amps but do much better on the low water end of things. The older Harris turbines were the external regulator type and had a pot for adjusting the field. they used the orig rectifier bridges which were internal and that is what I changed. When you pull the heaver loads it needed more cooling. I even added some holes around the base end of the alt to let more air through and cut allot of the top end metal out . the units run at a nice temp range now. The new harris system is a pm version and is better yet on the low end but not as good on the high end, so it is my 4th unit and I used it when the water is really low, Our when I have a big surplus of water.
