Elna had a production run of around half a million, so examples can be found relatively easily at estate sales and antiques dealers, and on classifieds/auction websites like eBay, Craigslist, OfferUp, letGo, Gumtree, Kijiji, Ricardo, Facebook Marketplace, etc.

This rough grading guide is a tool to help collectors, sewists and mechanics evaluate their Elna Grasshopper machines. Any grade is a subjective evaluation by definition, but there are certain benchmarks that must be met; it is particularly difficult to find a machine that truly deserves a grade of A. Machines missing essential parts cannot receive a passing grade, and I personally would never grade a machine with missing or damaged non-essential parts above a C, though exceptions exist as some parts are superfluous. The condition of high-wear, easily replaceable parts such as rubber feet and needles is irrelevant, although bobbins stamped "Swiss made" are highly collectible.
