Antique Stainer German violin

Hi, just purchased this Antique Stainer German Violin at a rummage sale. It was marked $10 but everything that day was half off so I paid five dollars it’s in what looks to be very poor condition It’s got a signature on the inside which I’m not sure what it reads. I don’t know anything about this it does appear to have some missing parts like strings and other parts please, I would love to know more about this violin like his age and any more info would be great, thanks
