From the numbers I'm thinking 3.62 open diff
The most common of them all
Still has a value £50 to £80

The important bit is 83bg mc 362

83bg = case type / 1long bolt = 7" / 2 short bolts = 7.5 diff mc = open diff 362 = 3.62 ratio

anyway... what is considered an «open diff»? isn't that a normal diff?

The numbers you need are on a thin ally tag which is held by one of the backplate bolts. These tags do get lost/corrode away/disappear. If you can remove the back cover you will find the ratio written in white paint on the rim of the ring gear. You will also be able to see the type of diff.

I know that part of the ali plate. but as some people refered the 'open diff' I started think if it was not a certain type of diff, but anyway it is only a diff that was openned, right?

You were right with your first guess. An 'open' diff' is just a diff' which doesn't lock in any way, ie a normal one.
