Beautiful machine! I knew it was an Elna because a friend of mine brought me one in June when he came for the convention. We had seen them at an estate sale of a sewing machine collector and he found it a couple weeks later at a local thrift store. There were two Supermatics, numerous other Elna models, 28 Singer Featherweights - yes, 28. I only bought one, a 1933 221. Many, many other machines of different brands, but oddly, no Bernina. I found a couple of Bernina accessory parts, but no machines. All had been serviced by the lady who collected them. I found lots of service literature, parts, a featherweight folding table, too much to list ;-) It was a very fun sale.
