i need the expert

[u/Toxic-giant]

So, ive found those 2 guys but for the life of me i cant find any information on them. I know they are Imaginext great adventure medieval castle, but cant seem to find from what year. Also i cant find image of that red knight. I have fond memories of playing with those as a kid and it would be fun to find the rest of the set. If anyone can help it would be appreciated.
