The Marconi 365

I've been looking for this Marconi 365 key for centuries ever since I Ieft the merchant marine. Only once I saw one of those keys and it wasn't for sale. I got this particular one several month ago and it comes from the classroom I took my morse lessons in the early 70ties. A thrilling idea! In the second picture is an old key (not a Marconi of course) from the same classroom just before the Marconi keys were ordered to replace them.
