I have read a number of reviews of what appears to be the same kit - my example had no manufacturers name on the box or the paper work - and I have yet to see any one who is, or has, experienced the same problems that I have. I can only assume that my kit is a very early production sample - when it appears there was no quality control or - I've been caught with someone's poor quality fake copy. Unfortunately I have no come back as the original local supplier is apparently out of business.
In the next day or so I will publish a full list of all the errors I have encountered with this kit - hopefully it might save some one else buying a load of crap like mine has turned out to be. The full list will be published on the P38 build page.
The list of problems I have found in the construction of this kit are now published on the P38 build page.
