Because of only one neck shape type for the 513 I supposed that they didn´t mention that in particular on their hang tags.
I checked a few test reports (German Gitarre & Bass Magazines of 2005 (513 Rosewood) and 2007 (513 Mahogany, now named MT) and Vintage Guitar (2007)).
They did´t give the child a name. All the authors paraphrased the neck profile.
The German describe it as a likewise W/F profile being smaller at the nut. This makes the neck looking tall (2005).
2007 they wrote the neck is smaller but slightly thicker. Like a fat C.
Vintage Guitar says: "Its playability is very good, and it has a comfortable, slightly-thick neck profile that doesn’t feel at all chunky, with a nice low/choke-free action, nicely polished and leveled frets, and excellent access to the upper frets."
But I discovered the secret other ways.
I checked price lists.
From 2005 to 2008 the neck profile type isn´t mentioned.
In 2009 they started with (German Meinl catalogue/price List) "513 Profil" or mahogany '513' neck (US price list).
In 2010 it´s the same.
But in 2011 either the German price list or the US price list introduce "Pattern Regular" for describing the neck profile.
In the following years "Pattern Regular" is standard information in the price lists.
