After posting one of my latest purchases on "My collection of Western theme..." Tiermann had asked if 3623 color cowboys came with a white horse with a molded saddle as one piece. When I reviewed the item again I was able to confirm that the white horse and saddle in this set are indeed two separate pieces.
What we know so far about one piece saddle and horse:
Schaper released such horses in sets 1982 and 1983 that were made in Malta.
(you can get a brown horse with molded saddle if you can find the Playmobil McDonald's Happy Meal toy from 1982 example below)
(or a black horse in such sets like 2955 example below)
I was also able to determin that in 1974 Playmobil Geobra released a brown horse that was one piece with saddle.
So now we need a collective group effort to find out when and in which set or was it a trial/ example piece that a white horse with molded saddle as one solid piece can be found.
If any ones has some additional information that can help shed light on the subject it would be appreciated.
