My favorite Parker, a12 g. 30" twist hammer gun (one of the Folsom "Trap Guns" discussed in an earlier thread) has me worried !
Granted, I'm the worrying type - but in addition to the moderate pitting in my bores, there appears to be a linear mark that must be either one of two things: corrosion that's occurring along the interface of two adjacent strips of metal that make up the twist steel (hence the linear pattern), or a crack between two adjacent strips of metal.
(This "line" does not run parallel to the bore's axis, it's a semi-circular "line" that spans an arc of approx. 100 degrees.)
My fear is that it might be a crack, and one of these days - it might separate & my left barrel might look more like an overstretched Slinky !
I've shot the gun for years (using quality RST ammo), and it shoots like a typical Parker: Great !
Dewey Vicknair is too busy - he said he can't take on any more work at this time. So, my question is :
Who should I send the gun to so they can inspect this "defect ?"
Does anyone know of a 'smith who has a bore scope, or other advanced means of checking this out ? Granted, a trained eye will probably suffice, but if modern instruments or testing techniques are possessed (x-ray, mag particle, dye penetrant, etc.) by someone - I'd like to send it to them...
I'm in PA, but if it needs to be shipped - it's just a little more money to ship it just about anywhere in the lower 48...
Please let me know your suggestions, or if these "lines" are commonly seen in twist (vs.. Damascus) barrels.
Many thanks !!!!!!!
