I been looking at this to buy but I would like a second opinion please would like to know if real or fake, has magnetic core and 3 piece frame I never seen one with a stamp on the bottom of the cross like this, anyone have any ideals who might have made this if it is real one? Thank you

If I am not mistaken, this is a Meybauer stamp.

Yes, it's a Paul Meybauer. There are a few variations of this cross in terms of materials and markings. All screwbacks had a cruciform backplate and a wingnut with DRGM patent number and sometimes 'PM' and silver content mark, if silver.
Here are a couple of examples.

It is indeed a Meybauer made cross.
