Hurricane instrument panel question

Can anyone confirm that the Hurricane Mk I or early Mk I had just the one starter button on the left or port panel, this is next to the magneto switch and marked ‘electric starter’, and that the fuel pressure gauge (red one) was on the early Mk I’s then replaced with the fuel pressure warning light. All of the Hurricane panels I have seen have the two pushbutton switches the other being the ignition booster coil next to the magneto switch, I always thought this was introduced from a Mk IB onwards but what about a Mk IA was it just the starter?

Thanks in advance.
