1971 deetail BRITIANS LTD figurines collection

Here is a collection of some vintage action figures. These guys belonged to my father. As a kid, he and his brother would go to the Toy Soldier toy shop at Mystic Connecticut. Each time they visited they would pick up a few and then they would play wars with them later. I think it took them about 5-6 years to build up this collection before they eventually stopped as they got older. Some of the figurines have broken guns/ missing arms. Some of the horse back riders are missing their seating, and two of the horses no longer have a horse back rider to go with them. I wanted to share the collection as I have a few questions. One of my main questions is how much the collection is worth. Although some of them are broken, the majority of them are in really good shape. (Especially the Japanese and British soldiers which are also more common than any of the others). Another question i have is if they are organized correctly. I am mostly talking about the two stray horseback riders at the back, i have no clue what army they are from. Im assuming they are either British or french but not sure if or which one is which. My final question would be is there any way to get replacement parts for these?(especially new arms) Anyway, thanks for viewing. Hope to post my louis Marx and co silver night soon! Let me know if i should post more photos ( possibly for each army)
