Thanks for all your comments and advice.
It's all been very useful and thought provoking.
I have decided to leave it sealed. With it being limited edition, albeit not that sought after, I imagine it will become
increasingly rare as time goes by.
I didn't pay that much for it, so may just shelve it for a while.
I have a 1936 III that I had CLA'd a few years ago to play with, while I save for another :)
