Body: <p>I have a large collection of parts and I came across this slightly chewed, possibly Technic, part. No numbers on it, just the Lego on the studs. It's 15 Technic holes and then a T-piece on the end with 2 studs either side. The head seems to have a slot through it. Any ideas?</p>

  That’s a [crane-arm centre](https://www.bricklink.com/v2/catalog/catalogitem.page?P=2351#T=C). It’s usually used in non-Technic sets together with the [crane-arm outside](https://www.bricklink.com/v2/catalog/catalogitem.page?P=2350b) to obtain a telescopic arm, e.g., for cranes or firefighter ladder trucks. The slit at the end is to insert a piece of string for using it as a cable crane.
