Parker DHE 12 ga Damascus Barrels

[OH Osthaus]

Yes Turnbull restorations are very well done,

to your points

#1 - assuming safe wall thickness - RST are as good as you will find. Polywad makes the "Vintager" shell which is another good low pressure 2 1/2 inch - off the shelf shells will likely be higher pressure. your chamber are most likely not 2 3/4 inch originally, but some were. By 1905 - smokless powder was in common use - but I personally stick to the low presure loads in damacus

#2 - not sure if you are in the USA - there is no standard proof house here. you can have it done at Birmingham England Proof house - not inexpensive, and you need an exporter to handle the transfer.

#3 - sure you can tube it - but if the barrels are good you don;t need to

#4 - look in the Hunting with Parkers forum for some pictures of other damascus DH's in action

as for care- its not much different than any good double - keep it clean and shoot it safely

we will certainly look forward to photos when you can share them. Join the PGA and get a letter on the gun- you can sometimes find some interesting history on the guns.
