Canon demi EE28 - help needed

Hi
I've already posted a similar help request at another forum. The problem is as follows:
I bought today a Canon demi EE28; it seems to be in a working condition, but I have a problem with the film-speed dial. The dial has some oxidation and erased numbers, and the plate seems loose, so I cannot use it reliably.
My questions are:
1 - When the film-speed dial is completely turned counterclockwise, does the 400 ISO/ASA mark stays at the six o’clock position ? Or should it stay in any other position ?
2- Wasn’t it supposed to be a reference mark or dot outside the dial to stop the desired speed at that point ??
Thank you for your help (and another thank you to the members who can point me a free dowloadable user's manual)

PS : I could try to find this by trial and error, or comparing with a reliable meter, however I am still not sure if I can trust the selenium cell, so I want to discard one variable…

I don't know if this will help you at all but I have a Canon Demi, just not sure if it is the EE28 that you have.

1. On mine when the film speed dial is turned all the way counterclockwise the 400 mark is at about 8 o'clock. It does move when you move the dial the other direction and then the dial notches its way over to the 400.

2. Yes, on the inside portion of the outside dial there is a black dot drilled and painted to mark the ISO.

Hope that helps.
