Hello! Based on your photos, you have either our S390-21 or S351-21. The only difference between these two products is the size of the shoe; you'll have to measure yours and refer to our dimensions to confirm the best match.

You'll also want to weigh your sash on a scale. Stamps ending in "90" like yours are an older rating system that is no longer in use. One of our options very well may work, but you'll have to weigh your sash on a scale to confirm which.
