They are inch based thread.
Can't you find these screws ? Where are you ?
Hi - I suspect they are UNC or UNF thread screws which are slightly more difficult to get hold of in Europe - there is a place local to me that should be able to match them up with new ones - I will check at the weekend.
Thanks for the offer of spare screws from the other guy but I'm specifically after shiny new ones. I'm also going to have the grey case paint matched with a colour match machine to make up some touch up paint.
By the time I've finished this EII+ should look really tidy.
