I need OAL case length and other dimensions for Starline 56-50 brass.

Can someone give me the case dimensions (especially the  dia. at the mouth and OAL) for the Starline 56-50 brass?  I need to find out how well it will fit in my original gun.  Also, are there two Starline 56-50 cases?  I see reference to 56-50 "Taylors" which has a smaller rim, is there as standard size case available?  Thanks.

Thanks, thats what I needed.  Before 56-50 was available on the market I had a bunch of 50-70 brass cut to length but an old partner stole it so I need some new brass.  The chamber on my gun is app. 1.1 inches so the Starline stuff will be long enough.   I am working on an improved, drop in solution to the gun's perpetual extractor problems, which I will write up when and if I get it working.  Now it looks like I need to get some dies and bullets.
