My list isn't as specific as some others in terms of measurements/barrel length. Sometimes I just like certain types of Parkers. I would say my wish list is as follows:
High grade(C, B, A or dollar equivalent) lifter in 12 gauge
A high condition shootable back action lifter with damascus barrels(12)
A Parker with a vent rib
A damascus gun with ejectors
A PH 20 gauge with twist barrels(flexible on barrel length)
A SBT - long overdue on this one
A straight stock gun with no safety from the factory
A hammer gun in 8 gauge
And last, but certainly not least is a 410 VH
Then I'll never "need" another gun
