Maybe I am missing something, but my list shows GP7, GP9, GP15, GP28, GP30, GP35, GP38 and GP 39.
Was there anything in-between all those numbers?

GP-18 and GP-20,at least.
Yea, but I think they were designations that came about after re-builds. Like the Paduca (re-) built GP10s on the IC. I think EMD had GP18 and GP20 designations too though.
The GP-8s,10s & 11s were just Paducah designations,as far as I know.
The GP-18 & 20 were EMD designations
Although there was a GP-20 Omaha version,done by you know who.
-2’s
GP22 was the first GP30 (EMD changed the model designation after the first one, snowman ILK in Houston’s favorite model)
There were SD-24’s but no GP 24’s… EMD’s marketing people started “tweeking” the designations between GP-18 and GP-35 making life confusing (But not as bad as Alco) as the HP derived from normal or turbocharged aspiration came into play…
You’ll also hear talk of GP16s sometime–these were rebuilds of former SCL-family GP7s and 9s.
There really hasn’t been a “GP15” model. The ones that were built were either GP15-1s (most of them) or GP15Ts, for C&O and Apalachicola Northern. Internally, those two don’t have much in common.
Didn’t the GN have a 1350-horsepower rebuild of something that they called a GP5?
I think that about covers it.
GN 900-915 were rebuilt from traded-in FT’s and were rated at 1350 HP and carried the EMD designation GP9M. GP5 was a class designation by GN, probably to differentiate them from standard GP9’s.
A few of them were rebuilt again by BN into GP28M’s and are somewhere in the BN/BNSF 1500 series.
