According to the year by year write up in the LMC catalog....
Monotube shocks were introduced in '50.
'51 was the last year for the stainless glovebox and upper and lower bars on dash.
It has vent windows which are at least '51, But the door handles definately look like push button's which are at least '52.
Optional factory installed turnsignals were introduced in '53, The turn signals shown there are listed under 'accessories' does that mean the same thing as optional factory?
I wonder if LMC is off alittle or this accessory sheet is not as old as it is supposed to look?

Maybe alittle retro pamphlet? Who knows?????????????????
