Thanks for your photos. Based on what I see here, you have either our S351-26 or S390-26, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

Your stamp also uses a different rating system than ours. You have a heavy duty spring here, one that seems to be rated to hold 36 pounds exactly (hence the 36 at the end of the code). That can be replaced by our 2570 option, which carries 33 through 36.
