That's a really great way to show off the differences between the two, and it must have taken a while to do.
You mentioned that there was not much difference in the barrels viewed from the top, but shown side by side the bottoms are definitely different enough to ask why do you think the ramp section that has the rocker on it is so much different on the left barrel then the right?In the original CZ, they did a machining step towards the front of the chamber to remove some metal. Not sure why, perhaps part of the more minimialistic design of the short-rail. In the later, Pre-B model, they didn't do the machining step, which results in a longer bottom portion as you see. My personal theory they made the change so that they could cut out the extra machining step. Functionally they're identical, as the affected section doesn't really come into play. The barrels are interchangeable and either will fire in the other gun (I know because I did it).
Also, I am NOT complaining it's just one of those after it's all done thoughts, it would have been interesting if you had added a B model to that demonstration and picture session just to see how much in any real changes were done.I don't have one, so can't make the comparison. But in my dreams a generous donor provides me a Stainless B for comparison! (http://www.ar15.com/images/smilies/anim_bannana.gif) As to the 1985 Pre-B gun, it's gone. I only purchased it for the slide release, and then sold it.
Correct
Are the B's as different from the pre-B's as the Short Rail is from the pre-B? and I am going to presume here you used the terms short rail and Pre-B as a means to identify them easier since they are both actually "Pre-B"'s?
However you choose to answer this or not is fine by me, I really only wanted to say Thank You, and say how great it was to see those pictures and the work you put into them. I bet you could make and sell a book of the different Pre-B/B models if you did it by doing the same thing. I mean if you had the pistols to do that with of course. I would loan you one or 2 of mine if that would help any if you didn't have them and did decide to try something like that. I certainly hope you do it again either with the 75 Pre-B/B comparison, or with other models. What about a ColtZ40 compared to the CZ 40? The CZ 40 was literally born from the ColtZ40 left over parts and continued from there to what is now.Thanks, though I imagine the logistics of loaning me yours would be more trouble than it's worth. As to the .40's, I never really had much interest in them. The .40 cartridge itself is a curious compromise cartridge. It's a good round, but I just never cared for it. 10mm on the other hand is an amazing round. And if CZ came out with an actual 10mm (a la the Bren 10) I would be extremely interested in that.
I figure this is just me, but something like side by side taken apart pistol comparisons would really work for CZ owners but especially collectors.Indeed, and short rails are rare. Yet those interested in them are VERY interested in them. Which is why I did this pictorial, to show fans what one looks like on the inside. And to see the difference between the two. To be honest, I really did the comparison for my own curiosity, and just brought the camera along. I've learned at my professional vocation that data analysis really happens during the report writing, which is mostly why I wrote the summary. Doing so helps me formulate and solidify my thoughts and conclusions.
Can anyone repost the pictures? Would love to see the comparison pictures. Thank you!
I see TinyPic died and lost my pictures.Try IMGUR.
