PING: Gary Istok or other old brick experts

Unfortunatley, I don't know the answer.

I'd try asking on Lugnet.  This newsgroup is about as dead as it gets.

The bricks with slots in the tubes are an old way they made the bricks.

The first Lego bricks made in 1949 had no tubes, but had slots in the sides to
allow fexibility for connecting the bricks together. The tube was introduced in
1958. See here for a chronology of Lego:

The slotted tubes might be in bricks made out of cellulose acetate. That
material was dropped in 1963, and ABS was used from then on. Possibly ABS
bricks did not require the slots for the binding feature.
