That appears to be an original Yale flat steel pin tumbler key with trefoil bow, sometimes called a feather key, and may date between 1865 and 1882 when they were replaced by a corrugated key. By 1904 all Yale locks had today's paracentric keyway.

According to my records, that is a #3 1/2 key with the A key section. It was used for padlocks 805, 8005, 806 and 8006 from 1902 until at leaqst 1934 and maybe longer but my record stops at 1934. The keyway was used for many different types of locks through the years but most of the keys in those uses had a bottom shoulder. The only other key that didn't have a bottom shoulder was the #1 1/2 but the blade for it was only .78" and I think yours is the 1.15" length.
