Crashes Bf 109G-6 WNr 15608 and 15698

[RolandF]

Prien lists in JFV 10/II WNr 15608 as 100% loss with III./JG 1 on 4th July 1943 due to engine damage near Makkum, Netherlands. The same day WNr 15698 is listed as complete loss during an emergency landing due to technical failures at Zurich, Netherlands.
Is it possible those listings describe the same a/c, especially because I have WNr 15698 as 100% loss with 7./JG 52 on 9th August 1943 at the Eastern Front. Zurich and Makkum lie only 5 km apart.
You all know my doubts concerning typed digits "8" and "0" on the 3rd carbon copy or whatsoever - either a hole in the thin sheet of paper or a fat, black dot...
