Embosed on the lid of the box along with the Hinsdale emblem is "23R", which seems to be the model number of this set, on counting the pieces once I took some stuff out which obviously didn't belong there are in fact 23 pieces not counting the box. Opinion on Channel 3 is that it dates from the 1930s, the guy I bought it from is a reseller, his belief was it came out here just in the last few years amongst the personal stuff of a US guy who had chosen to settle in NZ. Funny how we look at something and immediately come up with the wrong theory on Age and how it might have got here .......
