Mk2 'Pineapple' Grenade

[Achtung Spitfire!]

Picked this up a while ago as it was a bargain.(I don't collect WW2 grenades WW1 is my thing on the grenade front) but I suppose every grenade collector should have one. Anyway here's a Mk 2 Grenade also know as a Pineapple grenade. It was manufactured by the American Fireworks Co Ltd. I don't know who manufactured the fuse.If anyone can enlighten me? There's plenty of info stamped on top of it. All I know is that the fuse is a mid war manufactured M10A2. The grenade body retains traces of its original olive drab over yellow paint .HE Mk2s were originally painted yellow which really made them stand out but from around 1943 they were over painted with olive drab to make them less visible. They did however retain a thin yellow band at the 'neck' to Identify them as H E grenades. Remained in use as late as 1969 by the use navy.

I have previously disassembled the grenade but I'm reluctant to do so again as the pin is old & I don't want to risk breaking the ends off by straightening  them & then splaying them again.

Anyone know what G stands for?

Mark 2 Pineapple grenade questions?

Opinions on this Mk2 Pineapple Fragmentation Grenade please gents. It doesn't have a foundry mark unlike the grenade in the previous post which has the foundry mark AF which stands for the American Fireworks Co & also the letter G on the other side which I haven't been able to identify. On comparing the 2 bodies they are noticeably different. The yellow grenade is bigger. What is also obvious is the difference in the fragmentation patterns & the difference in circumferences at the base. The base itself is solid & shows no evidence of being filled in so I'm satisfied it's not an RFX. It has a later fuse which isn't relevant. Let me know what you think.

Cheers

 

A larger body and difference in fragmentation patterns. The one on the left has a uniform fragmentation pattern all the way around. The yellow one does not.

Note the difference in the base circumferences.

Nice items, the yellow grenade "looks" like to be a later model WW2 variant, similar to the MK IIA1 (used from 1943 onwards). Grenades were painted yellow from 1926 to 1942, afterwards they were painted a lusterless olive drab.  A yellow band was painted around the neck to denote HE filling. However this change took time, new grenades were to be repainted at factories and grenades that were already in the field were supposed to be hand-painted by the troops. The makers of the MK II A1 used both older stocks and newly made grenades to fill orders, and utilized the M10A3 fuse.  The Mk IIA1 was basically the same grenade as the MK II, just with a different fuse. Earlier MK II's used the M10, M10A1 and M10A2 fuses. Not all grenades were stamped either, however the fuses should be marked on the top lever. I must also say that I am not an expert on these types of grenades either.

Thanks for the info much appreciated. I was aware of the grenades being yellow pre mid 1942 & the overpaint in olive drab after that. It was just the difference in body design that has thrown me a bit. Another source has also said that not all grenades were stamped so it would appear that's the case in this instance. I value your opinion even if its not your field so to speak. Cheers
