Good lord..such minute little details...ive got along way too go before I can safely spot fakes....so can you help explain too me how to spot that the fake I listed is one piece?

To add to the answer Nick gives about how to see this here are a couple of pics to illustrate the three piece construction particulary the appearance of the seam.
The three pieces are an iron core visible as the black area with the swastika and date etc, sandwiched between, in the case of the EKII, two half frames front and back, in the case of EKI a front frame half and a flat back piece. The three are closed by soldering the front and back halves creating a visible seam.
This is a very good visible indicator and is easier to see in some crosses as over time it can separate to varying degree. However, one must be able to identify it properly as some one piece fakes have a cast line right where the seam should be so look carefully.
The pics attatched are of both EKII and EKI.
PS Please excuse the picture quality as I took them in something of a hurry but I think they should do the job.
Ah okay..i have a EKII and can see the seam on that one
