Hello Cousins'...
The formula I have for measuring diecast cars/trucks, is as follows.
Length converted to Millimeters. Divide by 4828.54 for actual scale.
Length xxx MM = xxx (÷) by 4828.54.
Results: The Corgi Fire engine measures exactly, 48.045174 It is not 1/50. It is a 1/48 scale model. Not sure why the paper work and seller stated 1/43.
Measured against a 1/43 Mack. the results are. 43.305291. using the same formula. See photo for both vehicles.
So, Lee you are correct, as the fire engine is closer to 1/50 than 1/43. When I compared it to one of the Macks I have, it turned out is was a 1/50, and I thought is was/1/43... (LO))..
The Green Mack is 1/43.
