Your photograph showing the Stb side agrees with the Medway restoration of which I have only seen the Port side in photographs. I presume the surviving Mk Is were modified to the current standard until they be came out of date so an aircraft that has survived such as the IWM MkIa is now more like a Mk V.
If depicting such an aircraft then it would depend on the date you were depicting it.
I will need to look at dated photos and see when the parts such as a bulged hood, external armoured front screen and one piece front fuel tank would be in use.
