Mustang Mk I

P-51A -> P-51C, which is the same as P-51B, -> Spit9/16 being the same as well.

Just in case that wasn't rhetorical

it's spitfire flying legend .

it quotes the weight for 1944 spit IX LFe as 500lb less .

just thinking would that be with the original 50 rounds of .50 cal not the updated 500 rounds from the MK IXLFe that had the same load out as the XVI?

so in reality they should be the same?

No Spitfire ever carried 50 rounds of ammo for a gun.  60 rounds per Hispano Mk I was as low as it got.  Also, 450 rounds of .50 cal ammo wouldn't come close to 500lbs.

The obvious explanation for the 25 vs 250 rounds is a typo/editor failure.
