Pictures would help. The first is probably a laundry mark, and the third might be the last name. Tom

What do you think Pty24949 means?

Yup looks like an ID mark. Looks like it was applied a long time ago with a ball point pen.

The other mark looks much newer and its in black marker of some sort.

So............

???Maybe a military surplus dealers inventory mark ???

My two cents. ( My Guess)

Whats the outside look like? Remember the old huge surplus stores they used to have? Even in the early 1980's they had ike jackets and ww2 wool trench coats etc etc .

This is what the outside of the jacket looks like and how could i narrow it down to a specific guy with the laundry number and libby?

The markings were both done by WWII-era laundry pens not ball point or magic marker...
