I will be making some reproduction brass caps and fuze bouchons for Japanese Type 97 or 91 grenades that are missing these parts and for anyone wishing to add some realism to a resin replica. I'm tooling up in preparation for making the first prototypes and I need to know the thread pitch and outside diameter of the brass fuze body where it threads into the cast iron top. If anyone out there has ready access to an original grenade, if you can please measure the thread pitch and outside diameter with a thread gauge or take it to the hardware store and try it out with different sized hardware till you find a match, please respond to this post with the size so I can order the proper size threading die. Thanks in advance
