Thread: Any able to measure a Hardy Gen 6 for me?

Hey looking to chuck one on a rifle of my old man's just wanting to confirm the actual measurement from shoulder to to rear of the barrel bushing and the actual overall length. Says 150mm overbarrel but I have no idea how long they are assuming the thread is.

I have the rifle with me and was going to thread it at work hopefully before I head home for XMas to save having to post the rifle home otherwise I'd just wait and measure it.
