These are Japanese market only magazines put out by the there well known TMS (Tetsudo Moekei Shumi) Company. These are loaded with illustrations, pictures and more.
These are truly scarce and show up in the States almost never so don't miss your opportunity.
With this lot you get 4 early editions: numbers 68, 71, 72 and 74. Even in Japan these are likely highly sought after.
These all have been read but are in remarkable shape given their age and use. You may find some tiny tears, creasing, marks, occasional small piece of tape, spotting and maybe a few pen marks (we saw one name written on a page so worth mentioning but most do not have this) and the like. See pictures for a decent idea of their overall condition.
We make these notes as a precautions and mostly for the 1st two even older lots but this lot is in really nice and tight condition with just signs of normal reading and age.
There are also numerous highly detailed drawings with measurements and they look like technical diagrams.
If you're a model railroad enthusiast then don't miss this once in a lifetime opportunity, we have little doubt you will never come across these early books again.
