Wow! How great are these 'nice to know' postings! I didn't know that, but I certainly will have my eyes open now. Suggestion about the gap: that way it's easier to get them apart perhaps?
Last week I popped into a charity shop just outside the Royal Free hospital and there was a bag of Lego in the corner, always happy to buy it as my lad is still very much into it, it was quite old judging by the colours and all quite basic, whilst rumagging my lad found a few bricks that were different, it turns out these were very old indeed, according to some research, these hollow bricks are pre 1957! ( Edit- 1954 - 1955 seems to be the year http://snakeandboris.blogspot.com/20...rick-1949.html ) are are made from cellulose acetate and not the ABS plastic that came in in the early '60s.
Im not clear what the vertical gaps are for, they seem to be random, some have two slots, some just one.
Anyway, I thought it was interesting enough to share.
yes, I know how grubby the white ones are.

Hi Jason I hope you are well.
I had a bit of a Google and apparently they fit certain glass panes in these special bricks...

Very interesting, every day's a school day. I suspect that the red blocks are just as grubby as the 'white' ones

I remember seeing some hollow Lego blocks as a kid in the early 80’s. I knew they were old but I didn’t know they were that old.
The slots in the link seem a lot neater than OP’s, wonder whether the latter might have been cut by their owner.Originally Posted by gregory
I think that’s just a very good condition brick, apparently the cellulose ones are notorious for warping over time.
