This is a window sash lift from a wood double hung window vintage 1950's home. Would you have this item? I'm trying to match the bolt pattern and spacing in order to match screw holes in the wood and the outline pattern from the metal edge. Thanks.

We have something very similar, yes. Check out our 20-007 wood sash lift, especially its dimensions, and see how well it matches your old hardware. If it differs in any way, let me know!
