I bought these about twenty years ago, just after starting in the hobby.
These have not served me well, I became a narrow gauger and these are mostly Standard Gauge oriented.
I have 65 volumes and the Index book which covers the first 42 volumes.
They are in four book/magazine holders, near like new condition.
$600.00 plus $25.00 Shipping (weighs 38 1/4 Lbs).
Most of the info is taken from the various Train Cyclopedia books issued over the last century.
