I remember Bill Benson most for being a member of the group (with Dick Kughn) that restored the Reading T1 2102 that the Blue Mountain and Reading is again restoring.
Actually, that was 2100. Here is a link to her current restoration
The Reading, Blue Mountain & Northern is restoring 2102. Here is a link
Dick Kughn and Mike Wolf offered an "O" Gauge model of 2100 (6-18006) in 1989. That was Lionel's largest steam locomotive to date. Here are photos of her, custom painted and detailed as 2124 by Reading Steam Guru and Wowak. Jeffrey Steinbacher of J.D.S. Limited Productions installed a fan-driven smoke unit and (as long as he was in there) a LED headlight.
