A WIP mk2 denix cylinder conversion ring for a chap to go with his Boo kit. Some minor changes from the earlier ones i've done thanks to more peering at ref pics (ta Bronson BB).
Also took a mold off of my Denix Lemat cylinder conversion ring, the holes are to fit metal 'hole caps' - the sort of thing used on flat pack units to fill in unused screw holes etc - make pretty good firing pins
