Persian Gulf Command Posted August 13, 2017 Share #1 Posted August 13, 2017 I don't believe there are any differences in the body design of a Mk2 Grenade from late-WW2 through the late 50's. Are there? Or, are there markings on the grenade that would indicate a post-WW2 manufacturer? Thanks in advance for any information given! Link to comment Share on other sites More sharing options...
vonmoen Posted August 15, 2017 Share #2 Posted August 15, 2017 I'm no expert on the subject but I would think that the U.S. Government had huge stockpiles of MKII hand grenades and drew from that stock until the M26 and M26A1 came along. Link to comment Share on other sites More sharing options...
War Paint Posted August 15, 2017 Share #3 Posted August 15, 2017 Most Post War MKII Grenade Bodies are marked "R.F.X." (Richmond Foundry). The earlier RFX's tend to be a better quality casting and truer to the classic form than later RFX castings. I also believe the post war grenade fuze thread is different than wartime production.

vonmoen Posted August 15, 2017 Share #4 Posted August 15, 2017 RFX grenade bodies were manufactured post WW2 for the MK21, a training grenade. Not a MKII. If you encounter an RFX marked grenade that takes a Vietnam era fuze, then it's a fake. MK21 trainers are getting harder to find because boneheads are converting them to "WW2 HE grenades". 95% of the RFX grenade bodies you find at gun shows, flea markets and online are bogus.

Svensson Posted August 19, 2017 Share #5 Posted August 19, 2017 Vietnam-era M204 and M205 series fuzes will fit in original MKII grenades. It's the M213, M215, and M228 fuzes that will not. Link to comment Share on other sites More sharing options...
rldarmstr Posted August 20, 2017 Share #6 Posted August 20, 2017 Something I ran across while searching for grenade fuse data. Mk.II Post WWIIAt the end of the War the fuze lever & bouchon design were modified to a split-toggle pattern. The new detonating fuze for the Mk.II was the M204A1 (A2). This was the primary defensive grenade used up to the Korean War. http://www.inert-ord.net/usa03a/usa2/index.html Link to comment Share on other sites More sharing options...
Persian Gulf Command Posted August 23, 2017 Author Share #7 Posted August 23, 2017 So, bottom line there is no difference regarding a WW2 Mk2A1 (solid bottom) grenade body and those produced after 1945. Korea to early Viet Nam frag bodies were all the same only the fuses changed. Correct? This is good to know. Link to comment Share on other sites More sharing options...
