New inch pitch chain

I dunno what any of that means, but it’s really cool old box.
I’ll educate you a little. Early bicycle chains didn’t have rollers. They were blocks of steel riveted together. They were inch pitch, sometimes called skip tooth. Modern chains are 1/2 inch pitch. IMG_1458.jpeg
Inch pitch drive roller chain. Later chain because it has rollers instead of blocks. IMG_0274.jpeg
A laminated block chain has no rollers but the metal slabs are thin sheet metal held together by the rivets. IMG_0102.jpeg
