mine is listed as ZHL- 506 so definitely a different version the Box looks similar though in that they use a decal on the box as apposed to printing directly to the box. This has to be the one folks were talking about being difficult to build due to no clear build instructions. I honestly thought that's what I was gonna get when I bought mine from Max. I thought I'd be able to figure it out. Turned out it came with instructions so I was happy to see those. That got me thinking Maybe the ones folks were talking about were the first Mess I ordered from ebay. I know what you mean about the A,B,C,D thing, The instructions don't tell you those letters correspond to the laser sheets I was like WTH I Guess I just have to look through every single sheet to find a part that looks like the part in the instructions while I was doing that I found the letter on the sheets and a porch light came on AAH-HAA I started the Log for that ship just incase someone had one without instructions but it appears the kits aren't exactly alike anyhow. So I hope my log is atleast good reference for folks to follow and get the ship built. I hope to have the planking in a couple weeks at most and I can get back to that build. I tend to build things fairly quick because I have a good amount of time to work on my models so I should catch up to where your at in a day or two. Ill keep posting a detailed build so hopefully you see something that will be useful to your Build and help you complete that one.
