Concerned about how FFL listed "firearm model" on form 4

I purchased a Lahar 30 (regular length)and about 2 weeks ago I efile submitted my NFA form 4 with my FFL. on the Questionaire copy I took home section 4C: just states LAHAR as the model and 30 caliber for 4D.

Is that sufficient or does 4c need to be listed as Lahar 30 as the full name? Wondering how pedantic the ATF is going to be. I could see the argument both ways as needing it or not needing it.
