How can I find what's my MacBook Pro Model?

If About This Mac identifies it as a Mid-2010 13" MacBook Pro, that is all the information that is normally needed but you can also get the following from Identify your MacBook Pro model - Apple Support

MacBook Pro (13-inch, Mid 2010)

Model Identifier: MacBookPro7,1

Part Numbers: MC375xx/A, MC374xx/A

Newest compatible operating system: macOS High Sierra 10.13.6

Tech Specs: MacBook Pro (13-inch, Mid 2010)

Regarding "A1728" see the following from https://everymac.com/ultimate-mac-lookup/?search_keywords=a1278

Because there are 12 MacBook and MacBook Pro models that match the A1278 model number, you may wish to lookup yours by Model ID or Serial Number for greater precision.

When one does as FoxFifth has recommended, one should see something like the following:

We do not need the Serial Number!

Click on the Apple menu at the top left of the screen, click "About This Mac."

I see you found my screenshot!

Yes, Allan Jones.

It’s a very good tool in helping people know how to find the information they often need, here.

I do hope you don’t mind my using it.

It would be courteous if you would attribute it to its creator, at least occasionally.

There was some work put in to create it.

I agree.
