Yes, digitally altered.
There are reports of a real LB No.5 prototype surfacing, though. Photos of this one will be posted in the next week or so. Sounds as if this one might be the real deal.

Fair go, it takes time to get that 70+ years old look down pat, this next one maybe a couple of days older.

Well, the photos of the LB No. 5 prototype have been posted over at canadiangunnutz.com.
I have no basis on which to comment on its authenticity.
It certainly could be a prototype.
Or, if someone wanted to replicate a prototype, it would look the same.
