Gill Sans Nova includes a single-storey a and a single-storey g in the font.

Thanks!
(Does this mean that Gill sans nova is an approximation....?)

Gill Sans Nova has alternate a’s and alternate g’s.
See the glyph map:

Thanks!
It seems that Gill Sans Nova is closer to this due to the alternate [a],[g] and the shape of the [l].
