How long was the standard barrel length on the early 318 Westley Richards?

How long were the barrel lengths of the three early 275 Rigby?

What was the muzzle diameter of the above?

A couple of pictures would be appreciated.

Thanks captdavid

"It's not how hard you hit 'em, it's where you hit 'em." The 30-06 will, with the right bullet, successfully take any game animal in North America up to 300yds.

If you are a hunter, and farther than that, get closer!
