I think this is a Tegenaria Domestica or T. Gigantea.
Can someone tell me from the size ?

The photo of the jaws and fangs from a dead body of spider. I am hoping that the size of the fangs will indicate which size of spider it was.
Hi, do you have a photo of the entire spider also? That helps us identify the gender, age, and species from markings, arrangement and number of eyes, and hairs, colors, and physical characteristics. The site isn’t programmed in a way in which you can add additional photos to an original posting. You can, however, post photos individually with notes that they go together. A collage of photos counts as one photo and will fit into a single posting. Either way is okay. I’ll see if I can work with the resources I have if you don’t have additional photos.

Hi, thanks for your reply. I don’t have the entire spider, just a few broken parts. I will try to post them
I tried to use the photos, but ID manuals require one to start with the entire organism and work down to details. I jumped forward in Tegenaria and the body measurements of diameter of leg sprawl and the torso are the measurements that are used for most spiders. The details that I did find (bugguide.net) were that some Tegenaria have been relocated to genus Eratigena. Eratigena have more robust chelacerae (the appendages that contain the fangs). Eratigena coras has particularly robust chelacerae. No specific measurements were given.
Many thanks for your kind efforts in response to my question. I only found the remains, probably of a moult, and I couldn’t extricate it from the web without pulling the remains to even more pieces.
However, I have spent £18 on a good field Guide of Spiders and I now see the difficulties.
I just hope for a better specimen in future.
Thanks
