My channel balance measures 9/16" wide and 28" long. Only marking on the balance says "2740DG". I think it is either a s351 or s390 but I'm not sure. Please let me know if you need any more info. Thank you.

The "shoe" on my balance is 1 1/6". The two I see on your website are 1" or 1 1/8". Is mine just worn down to 1 1/16 from 1 1/8"? Thanks.

Yes, it's very likely that your shoe just wore down a little from use. If it's 1-1/16" deep, then the Series 390 is your best bet.
