Replacement for crank handle and cover kits

Quick Learner from LA
Can I replace this two crank handle and cover kits with truth folding handle and cover kit (Product Code: 39-107FK)? I don't know how to find the brand of our current crank handle and cover kits as shown in the provided photos.
Could you tell me what is the difference between the numbers 21 and 23 in the two handles above?

Thank you for contacting us! The 39-107FK handle should work fine for you. As for the difference between "21" and "23" on your two handles, I doubt that there's any difference that matters. It's just a mold marking and can be ignored. 

Let us know if you have any other questions!
