Cant help with the summertime pack question but fwiw was on hoilday a few weeks back and took a tiki tour inclusive of the NZ transport museum in Wanaka,the amount of old English stuff in there was staggering to be fair,some beautiful Escorts but sadly didnt take pics or at least any decent ones.
And this wee gem even.
Sorry to be a bit off topic but thought you would like the pics.
