The gifting season is nearly upon us with December 5th approaching rapidly, so toy-stores are well-stocked. When browsing the shelves this morning (incidentally for a birthday gift, not on behalf of the holyman), was struck by this box illustration on the shelf.
The part 126a was introduced in the September 1921 issue of the Meccano Magazine (top-right of page 3), following on the part 126 'trunnion' introduced in the May issue of the same year.
The naming is a bit odd, as it is most certainly not a trunnion. The part started out as a trunnion-support, but somebody at Meccano got confused apparently and they named the support 'trunnion'.
The 2018 issue 'buggy' does look modern and of course has plastic shaped-parts as well. Nevertheless it is still very much Meccano and still compatible with century-old parts - it even contains a near-century old part. (There's also a strip part number 3 in there I think - that design is actually more than a century old.)
Today's Meccano is a brand owned by a Canadian company with its design-offices for Meccano in California. From what I gather, they are trying hard to be a modern technical toy including robotics and electronics and would not like to emphasise their heritage. With the amount of look-alikes and low-cost 'knock-offs' also on the shelves, I can imagine that it is not an easy task to catch the attention of children (and parents) today. And that's not even mentioning the ubiquitous Danish product with its technical bits.
Nevertheless, they still do have parts on the shelf - have done for a century. Good show, that.
