Lock for PELLA double hung window

A quick learner from Virginia says:
This the lock from a PELLA double hung wood window from about 1981-1982. Internal parts are loose and worn out, spring lost tension. I would like to purchase a replacement. Thanks

Start by comparing an undamaged lock to our 90-213 Pella lock & keeper to see if this matches up to your old hardware.

A handy person from Virginia says:
Not exactly a match. My striker piece has two screws securing it, your 90-213 shows 3 screws. Can the 90-213 lock be used with my existing striker?

Our 90-213 is our closest match and looks like a dead ringer for your old lock. If you're unsure about the keeper, show us a picture and we can work from there. The 90-213 comes with its own keeper so you could just install ours with two screws.
