Is this the modern version of the F7? There are four companies I know of announcing these engines, Fox Valley, Kato (they were first), Intermountain and Scale Trains. I have a Scale Trains one in the mail and I have my older Katos and earlier Fox Valley engines (where I added all the free standing hand grabs) and I am waiting to see what they look like and how they compare to my existing models.
Having added all those grabs by hand was tedious work and I can see why they might not be perfect in a production environment, mine certainly aren't, and a couple of them were nearly impossible.
