Where the label has worn away on the box lid, it could be seen that the Dutch label is a paper pasted over an English printed box. The motor inside is in a surprisingly good condition. With the paint good still and really no rust, this motor is altogether too nice to play and build with today.
Even the spring is clean and free from corrosion - like new.
The included instruction sheet is multilingual and also a bit strange. The Meccano company made the effort to print and paste a Dutch label on the box and then included instructions in English, German, French and Spanish. No instructions in Dutch.
Another strange thing is that the Dutch warranty slip is pasted over the remnants of a torn-out slip. From the remaining printing codes, both seem from the same era (printer code suggests 1931). An original 'U' (United Kingdom?) slip was replaced with an 'H' slip (Holland, likely). Seems very sloppy for such an expensive item. Perhaps needed to quickly fill an unexpected export order, but still.
Had bought this item to get a dark red motor to go with the period set for building. On the pictures of the listing it looked decent enough and was stated to be in working condition. When I got it, it turned out to be that this particular motor is too well preserved to mar with screws. It'll mostly continue being kept in its box. A very nice time capsule nevertheless :)
Below a larger resolution image of the instruction sheet, should you have one of these and be curious on its use :-)
