I have few H1 and H2 crankshafts dismantled, cleaned and ready to be assembled. The cranks are very tight, non-rebuilt cranks. I will build to your specifications. The price includes labyrinth seals (very high quality made in the USA) or stock rubber seals if you prefer. The shipping is free within the 48. It is best to reach me by e-mail, triplecranks@aol.com, or by cell (443) 752-1222. The options are listed below:
H1
Option 1 – Standard grade bearings with new slotted rods $930.00
Option 2 – Koyo bearings with new slotted rods $1015.00
H2
Option 1 – Standard grade bearings with used stock non-slotted rods $740
Option 2 – Standard grade bearings with new IMS rods (slotted) $840
Option 3 – Koyo bearings with used stock non-slotted rods $825
Option 4 - Koyo bearings with new IMS rods (slotted) $925

Again, these are sold outright with no core needed.

Edit was H1 pricing. Vesrah rod price went up on me.

How about this: I worked for the Navy for many years and had much to do with submarine components. Naturally sub stuff has to be very quiet so waterborne noise doesn't betray the good guys to the bad guys. That means the dozens of fans, pumps, motors, etc have to have very quiet bearings.

The Navy has pursued "quiet" to a high degree. It's accomplished by "gold plating" every detail and feature of every part of every item of sub equipment, the way it's mounted, and they way it's connected to the systems. At night when the shop was very quiet, I've walked past sub motor driven apparatus running under test to full capacity and it was so quiet the only way you could tell it was running was the ID tag was fluttering in the cooling air blast.

Most noise quiet bearings used in subs were selected and tested from Koyo over the counter stock and designated NT-3. No other world ball bearing manufacurer met Koyo's every day quality of race and ball geometr, finish, cleanliness, and consistancy.

Now is twenty years later. Things may have changed but somehow I doubt it.
