Replacement Surface Mounted Latch

A quick learner from South Carolina says:
I need to replace a surface mounted latch, left hand. Windows have other hardware that has, "MW" on it. I understand this company was bought out by Plygem. I see that the 26-419/420 and the 26-243/244 resemble it the most. Are either of them the right replacement part? If not do you have the proper in stock?

Hello!

The only difference between the two pairs you mentioned is the position of the bottom locking tooth and it looks like neither of which matches up to what you show here. Your bottom locking tooth is way, way forward while ours are set too far back.

With that said, it doesn't matter too much. The latch still has a snug fit and will be held in place by the jamb, regardless. It's not like its going to fall out. With that in mind, you could use either pair.
