Re: 59a - or 59ab
I'd sure like to see one of the 41A blocks so I could be sure for my own information but some folks say they are very much like the prewar 221 blocks and have thin cylinder walls like they were using the prewar cores in the post war core box. I hope someone comes up with one to photograph for the block ID thread some day. It would be nice to know what all the true characteristics are.
