I thought it might be worth sharing a photo of the Jouef 40 for people that haven’t seen it...The Playcraft items were HO, the mk3 was the only true scale model they made as the 40 was too wide.
It certainly does have a funny shaped conk on it.
It’s interesting to note that plenty of modern manufacturers have made mistakes too though - For example the Heljan 47 was definitely too wide, the first Bachmann 37 had completely inset cab doors which looked all wrong and there’s other models out there with the odd glaring error.
Interesting thread.
