Ive seen literally dozens of 700s over the years with pitted barrels. Nothing special about 700s in terms of barrel steel, its most definitely not seriously corrosion resistant.
No intention to indicate there was anything special about the steel in 700 barrels. Guess the pits must have missed the dozen or so I've owned--currently and in the past--and the dozens more that I've looked at. Hoping to hear from a Brit gunsmith about the prevalence of pitting in Brit doubles of the post-WWII (post-corrosive primer) era. Of course one advantage of British doubles is that the use of plastic wads isn't as common over there as it is on this side of the pond. They're more likely to go with felt or fiber wads for the simple reason that a line of guns could otherwise dump a whole lot of plastic in the course of a single drive (let alone an entire driven day)--which most driven shoots would wish to avoid.

The chrome plating which was applied at Wilson's when I was employed there in the early 1960s was of a two metal process, I'm pretty sure the base layer was copper. This layer was NOT used to fill in scratches. The heads were all polished by means of Set-up close weave & tightly stitched cotton cloth polish wheels which had glue applied around their perimeter & were rolled in grit. I do not now recall the actual grits used but first was an aluminum oxide wheel which was referred to as a Red Wheel. Next came one of silicon Carbide which was called the Black Wheel. Following this, they went to a brush wheel which was called a Tampico Brush. I was told this was made of some sort of Sea Weed. This w brush was treated with an abrasive embedded in a greasy carrier held in a cardboard bodied tube & had to be applied by rubbing it in every few heads. Also, this operator formed an inspection of the polish job & any with scratches were laid back to the other end of the container they were carried about in & they went back to "THE" polisher who had run them for touch up. This brush was followed up by what was called Hi-Polish which consisted of a loosely woven & stitched cotton wheel to which was applied a finer abrasive contained in a Dry Bar.
The heads went directly from the base plate to the final plate with nothing being done between the two. Any scratches which were on them when they went to plating Stood Out like a sore thumb after plating.
During my four years of employment, I did all of these operations, except the plating. That is I polished, I brushed & I high polished. Even though it has been more than 55 years since I last punched out on the time clock there, today if you gave be one of those wheels & an iron head I could still do those operations Blindfolded. I could not, of course, inspect my work blindfolded, but could do the operation.
Bottom line is all plating is not created equal.

Years ago I had the bores of two Rifle Barrels (muzzleloaders) hard chromed by a firm in Illinois called Marker Machine Tool co. I think they are merged or out of business as I cannot find them listed. These bores have held up incredibly well after MANY rounds of shooting. Does anyone know who does that now??

I heard all chrome plating is done out of the country now because of the hazardous chemicals envoled.

jOe is correct. Everything changed in the chrome plating industry after 1975. Prior to then the process created hexavalent chromium (remember the 2000 Erin Brockovich movie?), a potent carcinogen, and lead, cyanide and cadmium. The disposal issues thereof shut down most of the small operators, and it's my understanding that chrome plating remains a big business in Tijuana where the waste water can be dumped in the drain, to the Tijuana River (sewer) and then ends up on the beach in San Diego. There is a shop in Phoenix that is reported to haul everything to Nogales for the plating.
The post-1975 process is much safer, but the businesses must treat their own waste water - very expensive.

Bottom line is all plating is not created equal. I thought it may have been Wilson when you posted. My father had the Canadian distributorship for Wilson from the early 1950's until 1970. You must have produced some of the irons that came up here. As ridiculous as it sounds, small world.

Don't believe everything you hear. There are several places in GA that do plating, including chrome. Here's just one: https://www.chromeatlanta.com I have a friend who restores classic cars and he gets all of his re-chroming done in GA. SRH
May God bless America and those who defend her.

Same here, Stan. There are several plating shops in the SLC area, I send motorcycle parts to them fairly regularly for plating, stripping, etc. These arent big operations either. Friends who own body shops and other friends that restore bikes, cars, and antiques also use these same shops.
There are plating shops in Omaha that I used to use for the same purpose, again, not big operations.
