I'm sorry about your mom.
To attach picture, use the Photos icon just above this text box.
If you click on the 3 bar "hamburger" menu near top left of this page, you can see pictures of several models, but feel free to post picture here too, preferably front and back to distinguish some models. Unfortunately, each model requires different charger so have to get right one. When you do get it figured out, you can buy chargers here on the Fitbit store or from some retailers, or probably from Amazon - maybe third-party so not guaranteed by Fitbit but usually cheaper.

Sorry for the loss of your mother. It's hard going through personal belongings.
Here is a picture of the Fitbits, including those models that were retired. You might see one that looks like what you found.

I agree Charge or Charge HR (heart rate). Look on the back. If all you see is 2 contact pins (for charger), then it is a Charge. If it also has a raised section with a little square in middle with little circle above and below, it is a Charge HR. The 2 little circles are light emitters and the square in the middle is the receiver.
Actually the Charge and Charge HR might both use the same charger. Hopefully someone else will clarify that.
