Hi! I have already posted a message in an old thread here, but maybe I should have started a new one instead. My problem: I have an old pronto shutter (westar lens from a dacora digna camera) and I cant remove the middle element's housing. I have done it before for various shutters, even for rusty ones but now I can see no pair of notches for the spanner only one little hole that I cant figure out if it contains a screw that has to be unscrewed or it is something else. I haven't find information for this kind of situation anywhere in the web. Everybody says that the housing should be unscrewed as a whole. I am ready to drill another hole opposite to the one that I see and try to work it out that way, but I would like to know if anyone had any luck doing that. Or, if anyone are aware of this type of prontos. I cant believe that the manufacturer of the shutter just forgot to make another hole to make a pair for the spanner.
I was able to remove the centre element from a Pronto shutter as it was held in by a spring ring. This was removed by using a sewing needle to pry one end up. This is probanly what looks like a single hole, the gap between the ends of the spring ring. Getting it back into its groove is somewhat tricky.
