Lego Samsonite clear bricks – from set 045?
Which is the year of production of trans clear bricks?
All of them are yellowed and one is slightly warped.
Material is probably cellulose acetate.
Here below the codes under the brick coming from mould:
– brick 2×4 pat. pend. G 2, G 4, G 8, G 19
– brick 2×2 pat. Pend. B 3, B 16
– brick 2X1 pat. pend. 14A, 19A, 23A
Anybody knows?
