... but the designation VG.61 & VG.64,are they real one or fake ?.
Yes, that's what
Airborne2001 was asking. On his 'VG 60/VG 64 Revenant (Ghost)' link, you will find a host of
fictional VG 60 variants listed - a bubble-canopied VG 60 (HS 12Z), VG 61A (produced by someone other than Arsenal), VG 61H (with HS 12Z-55), VG 61N (presumably
Navale with unspecified armament changes), and VG 64 ("Late 1941" with an unnamed HS V-12 with "a Turbomeca supercharger").
Links in the specifications areas are to now-defunct
WesWorld pages. I think that should be enough to confirm that these designations are what-ifs. (Perhaps
Hood could confirm?)
Still, the Arsenal confusion continues ... On Justo's
Le Fana table (676.jpg), the VG 60 is listed only as a 'Jummo 213E' (sic) powered 1945 project. It is the 1939 version of the VG 70 that is listed with an HS 12Y-51. However, in the text (678.jpg) is says: "Elles menèrent au type VG 60, totalement re-dessiné et qui dut commencer avec le moteur 12Z, inévitable groupe des projets de chasseurs français de l'époque."
That bit about 'like all French fighter projects of the time' seems abit overarching to me. With so much contradictory information on VG 60 development, nothing is irrefutable. It seems entirely plausible that, in 1939, Arsenal intended to power a prototype VG 60 with an HS 12Y-51 followed by production aircraft with HS 12Zs. Or, at least, that's the story I am sticking with ... until someone can show incontrovertibly that an HS 12Z was planned from the outset
