On MS 410s

[Juha]

Hello all
In his article in Sept and Oct 1973 Air Enthusiasts Pierre Leyvastre mentioned that MS 410 record remains uncomplete in that time. The proto was MS 406 No 1028, and from first 16 or so MS 406s scheduled for conversion some remained hybrid (they have either the 4 mgs wing or the fixed radiator) and others were presumably captured or destroyed on the ground before or after conversion. Among a/c that were reportedly brought up to full MS 410 standards were Nos 1040, 1051 and 1052 which were apparently delivered to the Adl'A in April-May 1940, but there is no record of their success or otherwise on operations.
During the early months of 1940, Marché 1022/0 was issued which called for the conversion of 500 MS 406s to MS 410 standards and another contract which ... called for 150 sets of MS 410 wings. But by mid-May 1940 it had apparently been decided that, apart from the first 16 or so scheduled conversations all MS 406 conversions should be performed by ARAA at Clermont Ferrand-Aulnat and that these should be produced from damaged MS 406s...Also the change of gun sight, airscrew and the installation of GAL-Bronzavia ejector type-exhausts was planned... But no MS 410 had apparently left the Aulnat conversion line before the Armistice.

So my questions are:
Is it know today how many MS 410 conversions were made?
and is there info on if any of MS 410s participied in May-June 40 combats and if there is, how many and in which units?

TIA
