AFAIK, All J class locos were built with all axles
being roller bearing - J or J1.

The WW2 "skimp" was no shrouding, along with carbon
steel alligator crossheads instead of of the modern
multiple bearing type (light alloys were restricted).

Prince's book, as with most other references I've
seen, indicate the PRR reached sustained speeds in
excess of 110 mph with the J in command.

All per R.E. Prince, in "N&W Railway - Pocahontas Coal
Carrier.

Intriguing :-)
