I'm pretty sure that very early series 2 production had the lights in the grill too but quite quickly changed to having them on the wings - Must check in that manual, sorry if that makes me sound like a "know it all!
Amazingly I realize I have no recollection of ever working on a Defender.
Just checked this:
https://en.wikipedia.org/wiki/Land_Rover_series
Thought I was right about the lights in early series 2s
Na, Na, Nynana! Sorry, I'll go and stick my head down the toilet now for that disgusting display of righteousness!
1947 First land rover was called.... land rover, only anticipated production of a few years following end ww2.lights in grill.
People kept wanting them.
Redesign, oh bugger what shall we call it? What about land rover series 2, ok then from now on we will call the first one the series 1.
Early series 2 lights in grill, metal mesh grill.
Later series 2 , blast what shall we call it as it's not that different? 2A ok call it series 2A and put headlights in wings.
1972 update series 3 plastic grill no more impromptu bbqs using that.
Around 1983 and 1984 massive redesign using coil spring suspension, discs on front
Carp we can't call this a series land rover..... Just call the little one a land rover 90
And the big one land rover 110. Ok then will do.
Around 1987, That was dull name choice sex it up a bit. Ah I know Defender!
Will put carp plastic door handles on at same time and stop galvanizing the body cappings , that will save a few pence and they are lasting too long galvanised.
That's off top of my head so exact years may be slightly off.
