BOO!!! Mwahahahaha!!!!!
What is odd about the blocks that Zom. shows is that there are no 45 degree blocks nor round blocks, the ones in his set look to be 30 degrees or less and there is an odd number of them.
Also the wood looks to be a better quality with a better finish than standard play blocks.
Yes. The set in the OP ARE handcrafted, after all. I would guess they are much older as well. Probably belonged to some well to do family who had them made special, with their own case and everything. Those wealthy parents rarely allowed the rubbish of the unwashed to touch their "precocious" child's hands, let alone occupy his mind.
