I just recently purchased a Romeo 1 and I am very new to the X-metal arena. I noticed that the Romeo has 4 gaskets (2 upper and 2 lower) unlike the rest of the X-metal line. My question is this: I noticed the lower gaskets are held in by what looks like a "flat" screw. In other words there is no way to use the special screw driver to remove them. The uppers have the conventional screws to remove. So in the event of swapping out Romeo 1 lenses, I'm assuming I just need to remove the upper screws only. However, how would I replace the lower gaskets? (does the nose piece just "slide" off after the top screws are removed? Sorry but i've never done this. Any insight on this would be appreciated.
