Rfx, rfx, rfx, rfx!!!!!
I'll post this here also, because it really belongs here too, and maybe finally will help answer all the RFX questions that always seem to to come up again and again, and again. It's my theories and opinions about "RFX" marked grenade bodies. I copied and pasted this from my answer to yet another thread where these RFX grenades came up once again and caused confusion.....

I know this is a little bit of reading, but if truly interested, Please continue to read on...............all comments, possible corrections, or new previously unknown info on this issue are very much welcomed.................
The only solid bottom RFX I have seen, is the one in this thread by Eodtek

(this thread)
This body was an enigma to me...but think I have figured it out
Please continue to read............
First..... I have never seen an early pre-war, a WW2, or a post war "U.S. government issue" pineapple grenade body, that the body of fuze, and the neck of the grenade body did not "almost exactly match in size". The size of the neck on this RFX is much bigger than the base of fuze. No U.S. issue pneapple grenades will be found with this amount of size difference. (see pic) Anybody....Please show a real U.S. issue body like this if you have one.
(I do not think you will though)
To me, that fuze does not look like it fits that body properly but he says it does, and it's also 9/16 thread size, and the M10-M6 type fuze fits it properly. OK, I'll believe that, but.............more on this below.....
Please keep reading............
Secondly, from the interior view of this "RFX HE MkII grenade body" it looks like cheap cast iron, and nothing that the US Government would use for a HE grenade. Our grenades were cast from a certain quality type of metal, if I remember correctly a sintered steel or iron. We Definitely did not use a cheap cast iron for HE grenade bodies.
All my US HE grenade bodies, and every other one I have looked inside of, which is many, looked nothing on the inside like the supposed "HE" RFX grenade shown below, they all have looked similar to second interior photo below of the older HE body with the filler plug.
I think the RFX body in pics below is a cheap copy made by who knows who, that happened to be made with 9/16 threads instead of the larger threads everyone is used to seeing, and this caused a lot of debate and confusion. Look carefully at this RFX body and think about it. It's not a US issue body. It's a copy. Even the font of the RFX does not look proper to me. The inside is a dead giveaway, it's cheap cast iron.
I've also never seen any "original" green and yellow stripe solid bottom RFX marked grenades with WW2 M10-M6 series fuzes, and still waiting for someone to show one. Maybe they are out there, but I just don't think so.
***In my opinion, I think all "original" U.S. Gov contracted RFX pineapple bodies will have a hole on bottom, and are post WW2 M21 trainers, period. I do not think that RFX ever made a solid bottom HE pineapple body for the US government. ****
I also think now maybe all solid bottom RFX bodies that have popped up, are just cast iron copies of varying ages that have caused a lot of confusion for collectors. I would look inside All solid bottom RFX bodies you have or see, and if it looks like the one shown below, rough cast iron, it's a copy, NOT US issue.
But...... if some of those nice WW2 dated ordnance dept. "minutes reports" that have been shown here before, can show that RFX was a contractor for HE solid bottom MkII grenade bodies during or after WW2, or a period photograph is shown, then I will surely change my opinions.
