[Mg-mmm] headlamp lens?

[Carr&Edwards]

I'm still trying to sort out what's what among the bits of PA0935.  I have a
pair of headlamp lenses, in original Lucas boxes, Lucas # 551308; lenses have
U-shaped ribs, and are marked on the rim "No. D 714-3"; outside diameter
7-3/4".  I have no rims into which to test-fit them -- can one of you experts
tell me if they're correct?

Many thanks,
