The very fist reheated HF-24 was BD 831 which Winco Chopie flew on October 12, 1964 after production (See photo attached, and below). Groupie Das was somewhat unwell that day to do the flight himself.
It has now been confirmed that BD 884 in the museum in Bangalore is only a Mk IA. Wg Cdr IM (Chopie) Chopra flew it first after production on December 18, 1965. Thus, at least two Mk IAs were produced.
Winco Chopie’s logbook also has production serial number 006 which could have been made into Mk IR after he left for Egypt on deputation for flying the IBX, This might have been numbered BD 832 or 833 and could have been converted to Mk IR, the other perhaps to IBX. Final clarification on this issue should be available from Winco Tilak after he returns to Perth and looks into his (13) logbooks. He still flies as an examiner at times, probably filling the 14th logbook.
After BD 884 came to A&ATU for evaluation, Sqn Ldr (now AVM) Ajit Lamba did eight flights on it in 1969-70. I flew it in October 1970. All three of us listed it as Mk IA in our logbooks. It never had a clamshell canopy. I saw its small photograph on the website of the Museum. It does not look like a clamshell to me.
With best wishes,
