I think this is the one now at Pomona:http://cgi.ebay.com/Postcard-of-The-Improved-Climax-Locomotive-Hilt-Calif_W0QQitemZ6216948087QQcategoryZ29489QQrdZ1QQcmdZViewItem

The one in Pomona did run out of Hilt, but it is a 3-truck. It was the first locomotive saved by Norman Clark (of Roaring Camp fame) when with the R&LHS back in the 50s. He wasn't even 20 years old when he started writing letters to get these engines saved (in fact, I'm told he was kicked out of the R&LHS for getting too locomotives donated; the organization couldn't afford to pay to get them all there!)

Fruit Growers Supply Co. No. 3 is at Pomona. The builders date that I have is 1909.
