While care-freely playing with our Dinky Toys Fire Engines in the 1950s and 1960s, we had no idea that factory toolmakers had some worries to overcome with the production of this model.
As both the model itself and a comment on working conditions from a factory diecastmachine operator testify, the casting of this model was far from care free at times.
The repeated deterioration of the left hose reel box is such an obvious testimony. Above three stages, from top to bottom early 1950s, late 1950s and later 1960s.
Now I own one bare casting, having stripped off the paint from a very play-worn example, dating from before 1955 (as the now separate bottom plate shows the number 555, which was changed into 955 in January 1955).
Closer inspection shows an asymmetrical flow channel, undoubtedly added in the course of production, between 1952 and 1955, in order to ease a better penetration of the fluid zamak into that area of the die only, the right hose reel box. This means that â€“ contrary to the left reel hose box â€“ there was a problem from the inside of the die here. The left one will have had problems with the outside part of the die.
My curiosity into what more may have happened with the die, possibly showing more of such adaptations and cast flow improvements on the inside in the course of time, cannot persuade me to break up some of my other fine Fire Engine models.
So my question is if owners of open castings of this model could inspect their examples please, in order to see if other remarkable observations can be done in this respect.
Thank you in advance!
Kind regards, Jan Werner
