As the name already suggests, this is only an ALFA version of model (race) swap (players Human male models swapped into Blood Elf male with simple Helmet & NPC fix ).
Please , note that ONLY PLAYERS Human male Models are change , so NPC ARE NOT CHANGED (only helmets on human male npc removed).

Now about fixes :
Helmet fix--- in order to properly display helmets on new player models a simple fix ( HuM "helmets" swapped into BeM) , as a result Human Male NPC got Blood Elf male "helmets" .So, it was faster just to take off all human male NPC helmets.
NPC (Non-Player Character) fix --- in CharSections.dbc Hair texture lines remained unmodified in order to save NPC hair texture & colour , as a result "new" model (Blood Elf) has old human male hair colour.
Unfixed: Worgen males have human form which they share with human`s male model , so all worgen males have Blood Elf as second form instead of human form.
And some other minor stuff ..... :confused:
In Several words : human male player model ( 49;49) was assigned to new ( one more blood elf male ) model .
