top lever is left of center

[Mark Beasland]

I would not try that on a gun with a hard insert.

I have disassembled only four toplever Parkers and made an observation that was similar on all of them. After scrupulously cleaning the receivers and all components, I carefully assembled various pieces (except barrels) and came to the conclusion, that, in order for any of these four guns' toplevers to be to the left of center, material would have to be removed/peened on the receiver and/or locking parts.
