Talk:QF 4-inch naval gun Mk XVI

SIL?
At the South African National Museum of Military History there are two of these guns. One inscribed R.G.F 1937 NoS. 2755 and the other S.I.L. 1942 NoS. 8273. I assume R.G.F. stands for Royal Gun Factory, but does anyone know what S.I.L. stands for? Oh, as a sidenote, the breaches have definite sidedness when mounted on the twin XIX with safety and firing mechanisms machined and fitted on the outside as mounted. They are even inscribed L and R (2755 above is right mounted and 8273 left) --NJR_ZA (talk) 21:43, 26 August 2008 (UTC)

Don't quote me 'pon this, but I believe S.I.L. stands for Standard Inference Load. No idea what it actually means though; you're on your own there, buddy! Hehe! Aidan Biltner (talk) 12:35, 21 June 2009 (UTC)
