Smle grenade cup- markings survey

[lithgow1918]

Alright, I really messed up some of the nomenclature on this post and might have to restart it but here is what I am looking for;
Manufacturer marks on cups
Date on cup?
Any other marks on cups
Manufacturer marks on bases
Dates on bases
Any other marks on bases
From the research I have done these are all the manufacturer marks I am aware of;
RFI
S&B
SA
Bourn Brook
Farmers
HL-(possible refurb or other marks, as it was seen on an S&B base)
SIR
Now these are the contractors I could find for the cups in reading material;
Adams Bros. & Burnley-wwii
Lightfoot refrigeration-wwii
Lines Bros ltd-unknown
Metro Gas Co. (Australia)-unknown
National projectile factory-wwi
Components Ltd-wwi
S&B-wwi
Bowden wire Ltd-wwi
W.Ward & co Ltd-wwi
There are also 4 more WWI contractors not listed, and possible others for wwii, including some of the WWI contractors. It is also possible some of those manufacturer only made components, it's all a little iffy.
Also do y'all think I should restart the thread so it's more clear what info I want and what I know?
