1907 with Arabic markings

[jonnyc]

Actually the number is 405 since Arabic numbers read left to right; its obviously a rack number. The use of the diamond shaped zero might indicate use in the Egyptian army.

My Arab soldiers were always punctilious in maintaining their weapons!

If you'll notice, in the pic the "4" is backwards, so the pic is upside-down. I'll stick with 504............not that it really makes any difference.
