Any Help Identify 2 shell casings appreciated

[A B Sangster]

I recently inherited two shell casings from my Late Nan bless her,  i would really like to learn more about them as i used to play with them as a kid, I understand some markings but there’s loads I don’t or cant make out.

The first is an ALCO 18 PR II from December 1915, the second a 13 PR from 1916, however both have markings i am either unsure about or have no idea, they both appear to have been used more than once, any help would be very much appreciated.

The 18PR:

1: No idea, 2: Is an F?, 3: an S?, 4: an R?, 5: Arrow?, 6: possible second company under ALCO?-see following picture,      7: an A?, 8: R^L, Is this Royal London/ Royal Arsenal in Woolwich?, 9: No1/ IT? -see third picture.

Below the ALCO stamp ( American Locomotive Co i believe) there appears to be another company or something written, It looks like the first and Last letters are B’s, maybe a D thrown ontop and the A above, bit of a jumble really.

The first letters on the Primer are very faintly stamped, i can see No 1 ontop and below a T but not sure what the first letter is or would be, or what it means in general if I'm honest other than a type of primer.

The 13 PR:

1: VRY?, 2: 281?, 3: 051?, 4: I6?, 5: a T?, 6: C.f, is this simply cordite filled? I have seen the CF stamp but this has a smaller f?, 7: another company? Very faint- see following picture, 8/9: both also very faint, 90 w something with an A in a circle- see third picture, 10: an I?, 11: M.W.T/ EA?

Looks like an R and another letter ontop with a P below? 

no idea its very worn, 90? 9C then the circled A’s stamped ontop of each other.

Any information would be really appreciated

There are only odd bits that I'd know about, but I think 8 & 9 on your 13-pounder case are '9 Cwt', meaning it was intended for the '9-hundredweight' anti-aircraft gun, which has (as far as I know) a decent Wikipedia entry. R/|\L means Royal Laboratories wherever you see it.

Some of the markings are not so much worn as casually-made in the first place, because you can still see the machining marks from the casehead facing operation.

Your photography and labelling are outstanding.
