Thats a nice looking figure, I like the cape and fur jacket.
He has a lot of mixed parts, mainly from the western theme and I think he probably started out as the trapper in set 3397. The legs and body colour are correct for that figure ( not the arms though) and the dark brown moccasins first came out with that set in 1991, however the print on the legs must of been removed.
The shield was first released in 1986 with set 3329 Knight with squires and was used much later in the new look Knights sets released in 1993. The spear has been around since 1989 with the Native American sets and you must of removed the 2 lugs near the top to hold on the feather to make it look smooth.
So I would say that he was made after 1991 using parts mainly from the mid to late 1980's.
Yes, your right I do spend too much time with Playmobil.
