A friend on a different group is looking for manufacturer drawings (like Bettendorf and ASF) for narrow gage cast trucks. These were used by a variety of NG rr's under more modern freight cars as well as under tenders of Alco and BLW 2-8-2s.
They often had 4x7 journal bearings and typically 24 or 26 inch wheels with axle spacing's that ranged from 4 ft 2 in to 4 ft 11 inches.
Any suggestions or referrals would be appreciated
