Gosh this guy makes me so jealous! He just quietly works away and produces some of the nicest engines! From the RIGHT side this time, a Domestic Vertical, an inverted Otto, Bob's latest creation .. the PURPLE Mery engine, then his tiny International "Famous" vertical and behind that his 3 cylinder Fairbanks and a Domestic 'stovepipe' just beyond that. Bob's wife, Helen, picked out the color for his latest engine, the PURPLE Mery! Actually, the color kinda 'grows' on you! Good job Helen!
