the oval proof mark on a Belgium gun has an E L G in it

I'm familiar with the ELG mark and it's not it. The oval is horizontal and so are the letters. I am a computer Luddite and do not know how to post pictures
besides I doubt they would show up. [very faint]

check your PM's

here is a picture Herb sent me of the mark in question-
for the second one I tried to highlight the mark -

Herb- it's a gun or barrel maker's or importer's mark - not a proof mark - I don't recognize it but maybe someone will
is there a set of marks on the underside of the barrels? or the watertable

the mark on the watertable is mostly gone,it looks like it was a triangle but just
the corner of one side is visable ,other than that 16r,a serial#15852,and1941,70 Thanks,Herb
