I give old school workshops and clinics on unique modelling topics in all three scales that I model at home: N, HO and Lionel Legacy O. Here is my 2-folding-table workshop display on using real Nova Scotia iron ore for loads, scenery, structures and weathering that I gave at Maritime Hobbies and Crafts (where I work) in March. I am giving a similar invited clinic at the Maritime Federation of Model Railroaders Annual Convention in Sackville, New Brunswick in June (Google it). I will have several unique versions of scratch-built buildings from plans published in Model Railroader magazines from the 50s and 60s.
