Faked/Sleeved Titanic Barrels - pics

[TNR]

I just wanted to show some pictures and get some ideas about this Parker - such as any general idea WHEN and perhaps who did the work?

The story is short - my father purchased this DH (1903) at an auction around 1990 plus or minus 3 or so years. It wasnt a gun he was planning on bidding on but prices were low and he came home with several things.

Clearly its been redone - case and wood (which is original) and the wood and engraving are still nice. The barrels (originally 30" damascus), however, were sleeved and someone had the "damascus" sanded out and re-engraved with Titanic.

I've always wondered about the sleeving and if it was a quality job, but it's been a fun and reliable shooter for my pops the last 20 or so years.
