New To Forum and To Parker 28 Gauge

[John Taddeo]

A nice clear picture of the breech end of the barrels should tell the tale if it was monoblocked..

A faint seam line around the rim recess where the doner tubes were inserted as an interference fit to overbored chambers..

[Researcher]

My historical letter tells me it came from the factory as a 28 gauge.

Is that a research letter from the Parker Gun Collector's Association?

Yes, I can see it well, on both barrels. Also, the joint between old and new tubes is visible. It is the right hand edge of the engraved “chain”.

It's easy to see the boring line around the breach chambers. The old barrels ribs removed, barrels cut off & breach bored out & sleeved barrels inserted, soldered & rechambered.

Each barrel smith has his own method, but I suspect they were furnace brazed rather than soldered. Not that it matters a whole lot because this gun looks like a nice shooter, but yoke magnaflux would instantly show a distinct line, both at the breach and the joint between new tubes and original 'block'.
