Not seen this Model Miniatures, for six Porters before, so nice to see.

The post war one will have a 50,000 reference number on it, unfortunately not seen the reverse of this one so do not know as yet what it is.

Yes agree with you, there must be a trade box for the "Porters following on from the "Miniature period which ended mid 1934, for the prewar  "Dinky period 1934-1940, it is also possible that there may be examples in the Beige, Salmon or Yellow type boxes.
