Titanic barrel question?

[Ed Kettner]

I have a GH made in 1890. The barrels are upgraded to titanic steel with engraving and a matching serial number. The first question is, does anyone know why the barrels have ML after the number? 617xxML.
Thanks

Previous owners initials? I have never seen an ML stamp on a Parker shotgun.

First where was the upgrade done? At the factory, could be the initial of the person fitting the barrels

Sure the rib wasnt changed and the damascus barrels blued ? Any pictures of barrel flats .

A 61,XXX serial number range is way too early for Titanic barrels so they were obviously fitted to the gun at a much later date. I have never seen an original Parker serial number with alpha characters as a suffix and the only alpha prefix I have ever seen is engraved on the trigger guard tang as "No" for 'number'.
