Souvenir Iraq? ID please

I hope this is ok to post and photos work. Think this was in a Rucksack brought back from Iraq (not by me).
Stamps are;
105mm Fd
RW297
Lot 17
1980
RLB

Screen printed? L35A2. GDCW

What where who and when?
Thankyou.

Do you have a photo of the headstamp for us?

So far it appears to be a British 105mm made in 1980.

It is for the L109 gun of the FV433 SPG and the L118 light gun.

Thank you.
