Marvels have two different GAV needles/parts. One of these has the "half circle" Model A GAV (in fact the GAV and driver are interchangeable with the Model A Zenith) the other has a "hex" shape on the GAV needle and a matching driver.

The Model A version has parts available, the Hex version does not. The Renner Kit shown above appears to have the Model A type GAV needle.

If you talk to Renner they might have the other kind of needle to sell separately.

Or hang around your local antique auto flea market. You may find a seasoned veteran Marvel-Schiebler for as little as $5. They are EXTREMELY common. If you see a hex version - MAKE SURE IT HAS THE DRIVER because drivers are not available - although they can be made using a 1/4 drive six point socket and a modified Model A driver. But that's a lot of work.
