Help to identify scope

Can anyone please help me identify this scope & what it would be fitted to. It has no manufacture markings, only what looks to be a serial number. Looking at pictures on the internet i thought it might be an Aldis Bros scope. Any help appreciated. Thanks Shane.

How many offers so far? ;)

It's an Aldis "No.4" and was originally fitted to a SMLE in an enlarged PPCo. offset mount.

Here's a photo of the same setup.
