1942 Aerosphere makes no mention of Pasped and, as for Skylark, "Skylark Aircraft Corp of Venice, California, has become inactive." (This is understandable with the advent of WW2.) Also, "The two-place Skylark airplane formerly built by this company was described ... in Aerosphere 1941." There is no mention of either company or the airplane in Jane's from 1941-45 or Aircraft Year Books of that same era. When Perkins took over is unknown, as Pasped co-founder Pederson was shown in 1941, but not his partner, Fred Pastorius.

Wing had ailerons and flaps. 1946 aviation periodicals told of a "new twin-boom Skylark project" in three versions: 2p 246, 4p 446, and 5p 546. When the prototype appeared, it was as 447, with model number amended to fit the year.

1910 = 1pOB; 60hp Eldridge chain-driving two pusher props; span: 40'0". This was the end result of two prototypes that crashed, mainly because Smith was teaching himself to fly as he went along. A replica of this ship, built by Billy Parker and Bob McComb, is now hung on display at Ft Wayne Intl Airport terminal. Smith also previously built a "gasless air-ship," according to 1909 Jane'sno specifics given.
c.1915 = Three aircraft are said to have been constructed for Smith's exhibition performances at the 1915 Panama-Pacific Exposition by Al Mensaco. The use of "Smith-Curtiss Pusher" in a contemporary journal leads to an assumption of their being Curtiss machines assembled by Smith, or copies using Curtiss motors. Smith was pictured in several different types of aircraft during this period, most of them looking much like the tried-and-true Curtiss designsor at least faithful replicas.
Monoplane 1911 = No specs or data found.
1912 = 2pOB; 60hp Hall-Scott. Claimed to be the first tractor biplane built in the US. With his wife, Smith flew from Santa Ana to Griffith Aviation Park (Glendale) on 7/19/12, an ambitious cross-country flight at the timethe 45-mile journey took 01h:07m!

Not even the "De Luxe" addition helped very much. The aircraft would hardly fly. Smith bought it, increased the span of the upper wing, mounted the more powerful engine and flew it successfully. . After WW2 it was acquired by Hobart Sorrell in Rochester WA, who refitted a 65hp Continental, reregistered it as [N4940V], and renamed it Peer Gynt. It was active at least into the 1970s.
