This aircraft, which once served with the Japanese Maritime Self Defense Force as serial 4146, was photographed heading up a line of sister ships acquired for conversion to fire bombers, or possibly to support the conversion program, in the Hemet Valley Flying Service yard. However it was never converted but was spruced up and painted as Tanker 70 and now stands as a gate guard outside the co-located Hemet-Ryan Air Attack Base.

This Tracker never served as an airtanker, and was never officially registered. It is an S2F-1, ex BuA136745, which was delivered to the Japanese Navy on 12 Mar 1959 as 4146. In Oct 1983 it was acquired by Hemet Valley Flying Service as a spares aircraft and stored at at the Hemet-Ryan airtanker base. In 2001 it was restored and placed on display as a memorial. The text on the memorial plaque reads: "Dedicated in memory of Lloyd M. Venable - A pioneer in the aviation industry - Founder of Hemet Valley Flying Service - 1946. Born Oct 3, 1906 - Died Feb 1, 1991."
