Glazing bead identification please

A quick learner from Massachusetts says:

This is for an Anderson picture window that is about 48"x48". I believe it was installed sometime in the mid-1980s. Thanks!

Take a look at our 55-306 glazing bead. Andersen uses this on their picture windows for 1" thick glass. You will need to remove your beading from the sash to accurately compare your dimensions to ours, however.

I thought I had posted both pictures, seems like one got left out.

The P/N you suggested looks correct, except the little fins that snap in look different. Does this still seem right?

The 55-306 is slightly smaller than yours. The face is 11/16" to your 3/4" the depth of the locking leg is 11/32" to your 3/8". The width of the fins are 1/8". That said, the 55-306 may still work for you as long as the fins are the same width.
