34 black Spanner Square nuts, ¼" a/f, cranked, Meccano (c) (N) stamp, top, cranked end 73 mm long, 5.63 mm across at crank, 1.44mm thick. This from a charity selection with most of 1521 or 2712, ATV, 1523 or 2714 Excavator, 2004, M&S 2728 'bulldozer' digger and much of 6520 20 Model motion system. All this style. This style is also in new boxed M&S 2725 Microlite, 2005, and M&S Vintage Set 0530- I suspect this style, with what looks like a powder coating, coincides with Shenzen tooling
