I would never say never, but my guess would be no. It has been guesstimated that WWII stiletto production was approximately 10% of fighter production. That being said, and knowing there are probably only 5 or less known dbl pinned stag fighters from the era, that leaves us with little if any probability one was ever made.

Plus, the stiletto came out in April 1943, 6 months after the "permanent" switch to leather handles during WWII.
