I thought that was a Bucker Bu181 Bestmann (or a derivative), but I
might be wrong.

As Captain Tenneal would say, "Well, you're wrong." (Sticking my neck
out
here) I think its a 108. Dern few Bestmanns around. Anyone know for sure?

It was in fact a Bestmann or derivative. The key is the fixed gear as the Bf
108 retracts. There are or were then several Bestmann's flying in Europe and
they were also then in production in Egypt as military trainers. Even more
recently the type was offered for sale as the Aeropony with a modern
horizontally opposed engine.
