If I'm not mistaken, it'll look a little like this:
That's a Harald Moeller Bowie very close to a late 19th century English production piece. At least 3" - 4" of the upper spine will be sharpened, sometimes a lot more than that. Harald's variant shown here has a "coffin handle", fairly common. It's both functional and a "black humor visual pun".
There really wasn't a standard pattern of Bowie, they varied all over the place.
Jim H. is well known for good steel and high quality - and GREAT "bang for the buck" factor. The few specs you have (1.5" height by 12" long) suggest it'll be light enough to handle well, and given he's mainly known for swords I suspect he'll get the balance right.
The only thing some people don't like about these is the lack of "flexibility in grip styles", referring to how you hold it. The large upper guard messes up some forms of reverse-grip holds. The grip type is fine for utility, especially if there's an unsharpened area of around 1" just ahead of the lower guard (choil) so you can "trigger it", wrapping the forefinger around the lower guard. Triggering increased control at the expense of leaving that finger unprotected in a fight; historically many old-west fighters took that risk to increase tip control. Harald's specimen here has *just* barely enough choil, which is good unless you've got very fat fingers.
As long as you like point-forward fighting holds, this type of critter makes for a superb weapon. Mad Dog's Panther is basically a Bowie-oid, but lacking an upper guard he allows flexible reverse grips.
