Mr. C. Holt writes that he has had an active demand for his brass rail, which he has in three sizes suitable for gauges from “OO” to 3 ¼”. We have seen samples of this rail, and can recommend it as first class.The Modelmaker tended to plug their advertisers and Holt was one. Curiously, though, in his ad in the very next issue there is no mention of OO rail, just O and ½ inch scale rail.
In the March issue a reader wrote in expressing an interest “in model locomotives for small gauges” looking specifically for “scale drawings of an ‘OO’ steam locomotive, American Type.” Later in that same issue we hear again from F. D. Grimke. It is in a report on the February, 1928 meeting of the New York Society of Model Engineers, where were learn that he had “exhibited some ‘OO’ commercial clockwork and electric locomotives and cars which he had repainted.” Finally, at the end of this issue is an ad for the American Model Railway Company of E. P. Alexander that includes two items of interest: “Two OO gauge prints: P. R. R. P54 coach and 70-P tender” each of which sold for 35 cents. These should be HO scale based on what we learned of his early models in part II of this series.
Things pick up again in January of 1929 with this ad from E. P. Alexander/American Model Railway Company. It seems that they have a special shipment of OO gauge but it is clearly 5/8” gauge and also clearly of British manufacture. An expert in early British HO/OO could probably guess pretty closely what it is, but suffice to say for our purposes these models are not American OO gauge.
To conclude the year, in the December issue E. P. Alexander also advertised “Many OO Gauge items” in his full page advertisement for American Model Railways. Again, these I would think to be probably British HO/OO 5/8” gauge.
It would not be until 1930 that we see specific mention of American OO 4mm scale, which will be the final topic of this series.
