It is not possible to provide a price unless one actually sees and handles the set. And the purpose of providing a price is "what..?"
You can see what conventional MTH models of that type run. And the fact is that regardless of the estimated price these models are hard to sell. Professional dealers pay surprisingly little. The book value is relatively meaningless.
A friend who is a dealer recently bought a similar set for $250. He is reselling it for $600.
