My late great Uncle Philip had a Parker VH 20 gauge that he had re-barreled using the replacement barrel that Atlas Arms sold. I don't know who did the smithing, but it was one heck of a good job. If you looked real close, you could see where the old barrels had been cut off and the new ones had been installed, soldered or welded, and blued. Back in 1977 he was getting rid of his gun collection and I got his Winchester Model 52 target rifle. I didn't think about his Parker or his LC Smith 12 gauge, at the time.
