Breed ID for inherited chicken

Marker as nsfw because while she was alive when the pictures were taken she looks unwell.

I inherited this bantam and her sister after my grandmother passed away last year. The birds are quite old and I've not really seen her lay eggs for me to incubate to keep her line going and unfortunately she has passed away. It's not the same but I'd like to know what she was and maybe get a couple chicks in honor of my grandmother. Any help is appreciated. My grandma is the one who made me love chickens and I promised to take care of hers, but due to their age it's been a rocky journey.
