In this hobby, one thing is for sure that your collectible will never depreciate,, only if you are careless with it. Do as Dave says dont touch it. As time goes by so does the value go higher.
Even though it is not considered "Fine Art" by those who dont recognize the historical significance of it,,but it still remains in the same arena (antiques) for those who do collect it and see it as Art. True craftmanship is a form of art. In Modern times now, this craftmanship is absent from all things made. Most of the products made these days are "Junk".
Headees you have a great piece of history in your possession. Even though some will say there may be some faults with it,( no disrespect intended) which may be true but beauty is in the eyes of the beholder and as long as you like it, thats all that matters
