Tank Shell ID help

[skyboy09]

Helllo members;
I would like some help on identifying what i think is a tank shell casing, in regards to its country of origin and possible the year.
Sorry as I do not have a picture but these are all the markings I could read off the bottom

105x67 DM 60
LOS DN-2-14
What do these markings mean?
Cheers!

Well looking in the above 'Guide to Headstamps' sticky thread, I see that DM stands for the ordnance factory in Des Moins, Iowa- the 105x67 is the caliber and case length usually, so this is a 105mm round, and I'd expect the 60 is the year- 1960. Not sure what the LOS, etc. is but I'd bet it's just a lot number. The M60 Patton mounted a 105, so maybe this is from one of those- if it's a tank round that is, since 105 is a very common artillery caliber too...
