Victorian sofa with matching chairs

This sofa came from an estate in the 20s as best as we can tell. Not sure if it was passed down from the generation before the 20's or not. We think it went through a fire in the 60s and was reupholstered at that time (late 60s perhaps early 70's) Without removing the upholstering we can find no identifiers. There are two matching chairs. It has metal caster wheels on the bottom. 2 seem to be very old and original and 2 newer (from the 70s I would guess). We think it is authentic and not a reproduction. It's quite simple, but beautiful.
