That's an A806 which, if the water level switches are original, was manufactured between December of 1968 and February of 1969. If you have a serial number we can date it to the exact month and year.
Not a SS model those are the three wash temp buttons + the two rinse temp buttons, the SS versions of this machine had a different fabric PB switch set which had the two extra buttons for the SS.
This machine gives you three speed cycle choice buttons for Permanent Press, Normal and Gentle. Later models like my 1972 offer four choices of spin and agitation speed.

I think you're right. This is the first early style 806 I have ever seen that had a 4 button tall tub water level switch instead of the common 3 button. This one is REALLY rare!
The four speed options came with the introduction of the true Permanent Press cycle with cool-down. This was introduced across the board in February of 1969. Before this, the only machine that offered a true cold-water cool-down was the A906. The Wash-n-Wear speed button simple agitated on High and would spin on low.
Again as I said above, if the 4 water level switch is original (and these rarely failed) it should have a serial number dating it either December 1968 or January 1969.
It is also entirely likely that the WL SW was replaced at some point as someone already pointed out, and it was considered a proper substitution to use the better four level switch on any large tub machine that did not come with it originally. And while WL SWs did not fail that often we certainly did replace enough of them to keep at least a 1/2 dozen different MT WL SWs on each service truck.
It is always fun to do a little detective work and if someone here gets this machine they can easily check the date stamp on the WL SW and other electrical parts.
That said, if you are all handy with the "Frankensteining" of things, you could somewhat easily make the LDE309 into a back-lit unit if you can find a spare 806 or 808 panel around....
Well, hopefully someone here will be reading this thread and offer something. Other than that...it's a waiting game. CL searches, visits to appliance dealer's graveyards, estate sales...that's the thrill of the HUNT!
