Up/Down barrel movement
 

What is generally wrong when you have vertical play in the barrels? Your top lever is left of center. Is the locking wedge not seating all the way? Worn, dirty or other wear? Thanks in advance.

Vertical play in the barrels would generally be associated with bolt bite wear I believe. You can change out the bolt or rework the bolt and or bite. Might even be able to install a new wear plate entirely I suppose. Are we speaking of a Parker ? If so what is the year of mfg ?

Most hammerless Parkers that went back to Parker for most any reason after 1910 had the replaceable bolt plate and bolt installed at no charge.

1883 Grade 1 10 gauge.

That would be "pre" the replaceable plate Dean alluded to.

Pretty likely it never had a wear plate at all, just the bolt engaging with the flat bolting surface of the barrel lug. This premature wearing of these surfaces was the reason for the invention of the hardened plate that was soldered in place, then the pinned replaceable bolt plate and finally the "shouldered" plate.

My guess is that it never had a hardened plate installed and is the primary reason for the up and down looseness.

The only time that a soldered in pate was used was in the event of some repairs and I have only ever seen it on VERY early production hammer guns.

Soldered in bite plates were never used in the course of regular production. Just the pinned in flat plate in 1910 and the pinned in stepped plate in 1915.

Right.
