When people refer to "older style Arabs" they generally mean the more squatter, big hipped, big bodied with lots of bone Arabians instead of the stretchier halter types that are more popular today.
I have an older mare with the same sire line as his sire - Royal Zaltar.
There are a lot of Straight Babson Eygptian Arabians in there.
Preacher Man has a Skowronek sire line.
Hal Gazal was a great producer and out of a Pure Polish sire.
Now, Crabbet breeding isn't exactly a type - You can get Crabbet CMK Arabians, or you can get Crabbet Al Kasma, Badson, Straight Eygptians.
So while he has a lot of Straight Eygptian breeding, it is mostly Crabbet.
It takes a lot to figure out. Especially when you get a horse that is Straight Russian, but 100% Crabbet. LOL
A Crabbet Arabian is a horse that traces back to Crabbet Park Stud that were imported by Lady Anne Blunt - Mesasoud was a founding stallion and was bred in Eygpt.
So, depending on what type you like, Crabbet can be good.
This guy isn't a stallion I would use personally, but I prefer the CMK lines - which tend to be more solid then this fellows Eygptian pedigree.
