Need replacement window screen knife latches for Andersen window screens

Question

These window screen knife latches are from Andersen double hung windows installed in 1998 in Pittstown, NJ. The builder was Toll Brothers so probably bulk purchased. One screen frame has a label A-X7164; don't know if that helps identify the knife latch. Can't see an identifier on the latch itself. There are several different size and types of screens, but the knife latches are all the same except for different left and right sided versions.

Hello! These are definitely old Andersen brand latches, but I actually don't think that this exact design is made anymore. I think the best modern replacement is going to be the 70-226. This is also a genuine Andersen part and even has the same general design. The only major difference is the locking tab. Look it over and see if you think you could still get this to work in your frames.
