One of the "Sears AyA" guns (and I think it was the Model 100) is almost legendary among Spanish gun enthusiasts. Apparently produced only in a small number and sold for only a year or two, it has been likened to the 21 in quality.

Later versions are not as good, so I'm told. There are several Spanish gun forums where this is discussed in detail.

These guns are real sleepers since most people think J.C.Higgins guns to be low-grade.
