[Healeys] front wing cut-out

[Brits'n'Pieces (Eric Frenken)]

Hello,

I know the height of the wheel cut-out of the front wings changed between
BN1 and BN2, but I don't know the exact change point. Was this identical
with the change of the model (BN1 to BN2) or at sometime during the early
production of the BN2? And, which model had the higher cut-out?

Can somebody please enlighten me?

Thanks

Eric
