Found this on the website listed below. Looks like it might be in storage in Springfield, IL.

231, HP.137 Mk 1, Line Number 32, First Flight 3 November 1969, Notes: Line Number is out of sequence. Initially transferred to the International Jetstream Corporation as G-AXLO on 15 November 1969. It was then delivered to the Di Georgio Corporation on 29 November 1969, who sold it on 12 February 1973, to the Riley Turbostream Corporation. It was re-registered on 19 March 1973, as N7RJ, and apparently carried the titles â€œLife of Riley.â€ Riley Turbostream sold it in November 1974, to Jetstream Incorporated, who sold it on 9 December 1976, to Consolidated Airways, who in turn sold it on 18 April 1977, to Industrial Park Aviation Incorporated, who finally sold it back to Jetstream Incorporated on 28 April 1977. It was then leased to South Central Air Transport on then same day, and ultimately returned off lease to Jetstream Incorporated on 15 December 1977. It was then leased on 16 December 1977, to Air Illinois, before being withdrawn from use in October 1983, and placed in storage at Springfield, Illinois. As of 28 September 2008, this registration is still assigned to this HP.137, and is listed as valid, under the ownership of Jetstream Incorporated of Dallas, Texas.
