Manufacturer code? - Olympus Pen EE-S

Hi,

I have bought an Olympus Pen EE-S film (I assume mid-1960s) camera and would like to know the manufacturer code to let me know when the camera was made.

Other forums say remove the pressure plate (done) and the 2 digit code will there. They don't say where exactly. Does anyone know and can you send a photo indicating where the code is?

Thanks

Matt

Followup. Other site suggested having a look under the pressure plate, which I did.

The printed red 2 digit number

54

Apparently the 5 = the assembly plant

And the 4 is the last name of the year = 1964?

i'd be surprised if it were any different to the trip35system: 5 = 1965, 4 = april.

Thanks zweeko, that makes sense to me too :-)
