Back from the ASYLUM (Europe's largest Steampunk Convivial), where I was able to deliver this little item to it's new owner:
It comes in a velvet lined box, and has a pair of tools and a flask of liquid plasma:
You might just be able to make out the label, and that it is "My Favourite!", according to one N. Tesla:
Delivered by hand to it's new owner, one Mr. Robert Rankin, the well known wit, raconteur and writer of far-fetched-fiction, this now completes a pair of rayguns, the other belonging to his good lady wife, Lady Raygun, which may be seen here.
The Commodore was most gratified to receive his raygun, and I shall hopefully soon have a picture of the presentation to share with you.
