Sears cars were made from 1908 to 1912, but they were hardly unchanged. There are many difference between early and late cars, the most notable being the engine, which is totally different. I have an extra Sears body. It is disassembled and probably not complete, but would make a great pattern. It is for a long-wheelbase car, however, I believe it is almost the same. Fortunately, I also have my dad's complete and original 1910 model J in the garage if you want something to look at for patterns also.
