Hi Glenn
The mystery could be solved.
What a difference a day makes, being fortunate today to examine another casting.
Here is a photo (taken at an angle so we can see mould number position) of the container WITHOUT number paired with a RW body with thick axle supports, the brace on the cross member and wide tow guide.
The container has the 1.5mm tabs, bumper and the rounded thin rear brace.
The lettering on the bottom of the container WITHOUT number has Nº 47 cast but with capital N with dot under o.
The lettering on the bottom of the container number 2 has the NO 47 cast in capitals
In the second photo I have also highlighted that the lettering TIPPER does not line up with lettering in line below when the two castings are compared.
So it appears that the mould WITHOUT a number is indeed a new mould
It also has slightly bigger holes for the tipper axle as well as the step on the thin brace
WITHOUT number Tips to 46 degrees
The other number 2 mould tips to 33 degrees
Container Number 2 = 1.0mm rear wall thickness measured at the top
Container WITHOUT number = 0.75mm rear wall thickness measured at the top.
I think this is most likely the same variation where Antonin’s tips to 90 degree. This one is stopped by a cats whisker thickness by the casting from tipping past 46 degree.
Now, I should have noticed this before I sent through my previous detailed post having studied a SF container WITHOUT number but I was thrown by the very proud ejector rings which gave me the impression of having been in use for a while.
The new mould without a number has ejector rings which are flush.
I think I may have counted too many treads of late and my eyes are missing the obvious.
Glenn you might have to put that SF 47c back in the collection.
