This is the 9½ version of the 40tooth E74 

Britool Ratchet.

The last couple of photos show the two similar ratchets that I am 

selling - the longer one very slightly more used than the 9½" one.

This one (the shorter of the two) also has, what looks like, 

a black japaned finish to the socket shaft instead of chrome.

If you wish to be fussy I would advise you snap up your 

preferred one pronto, as someone will if you don't.

Realistically priced for tools of this quality and in this condition.
