I often look through old (sometimes ancient) issues of MR and it seems that there is an excellent supplier of cast metal and lost wax castings (whatever they may be(?)) called KEMTRON. There is a HUGE book on model railroading I got from my local Fremont Library entitled: "The Complete Book of Model Railroading" by David Sutton, copyright 1964(!) In this book it shows an extenvie array of kmetron parts, mayn of which are very useful and interesting. My favorite, perhaps, is what they call "conversion kits" where you take widely manufactured locomotive and modify it. In the case it's a 0-6-0T that can be modernized, industuralized, or aslo converted into an 1800's stlye model,all of which look great. So what happened to this company, KEMTRON?
