I don't think the first Astros came with a handle. From the first and second appearances of the Astro in Randall catalogs 16 (1963-64) and 17 (1965-67), the first only offered a handle as an extra cost option; the second had a micarta handle as standard, but increased the price $5.00. (The second catalog showed no increase in the Model 1, and nly a $1.00 increase in the Model 5.)
Randall began selling the Astro Model 17 in 1962. Each astronaut received one, as did the Head of Project Mercury. Two spares were made at the time. Two were donated to the Smithsonian Institute.
