Ham stopped making the side spring safety lanterns in 1897. The only image I have found is in the 1891 Ham catalog (available at lanternnet). It shows the #0 SSS in both round-tube and oval-tube versions and both have two orbital globe wires. According to Hobson, it appears there was a round-tube version with one orbital wire made 1887-1897.
