likely S380 24" compatible part - need confirmation

Question

Hi, I need confirmation if my window balances are S380 24".
Here is what I know, the length of the metal is 24" the width about 9/16"
The top and bottom nylon pieces lead me to believe that it is a S380 since it is 1" in depth.
The big mystery is the stamping on the metal. Referring to IMG-6903.JPG it appears that the stamping is as follows:

23B N

this can best be seen from the part on the left.
The "2" is very faint. The "3" also is faint. The "B" is easily visible.
The "N" is easily visible. Also visible is a symbol similar to "

Hello! A stamp of 23B usually corresponds to the 2340 stamp option on our balances. If you have any doubts, though, you can always weigh your sash on a scale and refer to the chart we show on the S380-24 store page. That will tell you for sure.
