Is a quaternary salt of an imine possible?

Can an imine with a methyamino group form a quaternary salt with a mineral acid? For example N-Methyl-1-phenylethanimin.HCl (A.K.A. acetophenone methylimine HCl).

Yes, iminium salts exist. However, most are not isolable.

http://en.wikipedia.org/wiki/Iminium

A fully alkylated iminium is "tertiary", because there are three substituents ("quater-" implies four)

Thank you for the heads-up, it is a great help to get a pointer in the right direction. Ok it's tertiary in this case because of the double bond on the nitrogen, thanks again.
