Confused on model

[Just getting started 22]

I purchased a Wheel Horse a few years ago from a gentleman on Marketplace saying it was a 64' 754 7hp model # 48046. Now yesterday I listed it on Marketplace, this guy sends me a message today stating this model #48046 is an 854. Could someone clear this up for me. I don't know how to get 

pictures attached, sorry. It has a 754 lettering on belt guard, which I understand that could have been switched, but it still has a K161S engine in it.

So, he sells m a 754 and now years later tells me I have an 854? Thanks, Dano.

For me, if it has the 754 belt guard and a 7hp Kohler then I would go with the 754.  @gwest_ca may have a list of model numbers which may tell you what it might have been from the factory.
