I agree with your reservations -- not a Bennington.
Is your sense that it's a lighter or heavier marble?
From the pictures I'm leaning toward a newer, more dense clay than a Bennington would have.
That's a neat bit of history.
Disappointing developments but you can display it all together in a Riker case. Still a nice thing to have in your collection.
Marbles are likely Vacor. It would be cool to have that header. Would be interesting to eventually learn if there is a date on the header, but would be nice to have it no matter the year.
I'm missing something. I'm referring to the sharp shooter bag header. That looks "real" and interesting to me.
Your avatar IS beautiful if that's what you thought I meant.
William, is yours metal?
There are some nice precision calipers which don't have metal. I haven't researched or invested. I actually do use metal, but I worry about damaging the marble.
Oooh, I would immediately have said Alley when I saw the photo.
But then reading your text reminded me that some of the Heaton find included marbles that I would have immediately called Alley. Off now to see if blue and green is one of the Heaton combos.
Plastic calipers can be had for very low price.
Or you could measure with two blocks of wood squarely against the ruler and the marble in between the wood blocks.
But, yeah, non-metal calipers give a quick, safe way to measure.
Marblenewbie, yours are called Fried Marbles. They were a fad in the 1960's but may still be being made as decorative pieces.
They are made by subjecting marbles to very high and very low temperatures.
