7th Doctor calculator thingy

[Crackers_Props]

Hello,
Not posters here before, but I was wondering if anyone can help me with this little dohicky

Does anyone have any idea what this little thingy the 7th Doctor has in remembrance of the daleks

It's an abacus. Seven often worked things out on it.

Thanks! I've done a little digging around and they don't come cheap!

I have a very Doctorish habit of pulling strange things out of my pockets to the bemusement of friends and strangers so I'll have to get one lf these lol.

They made fun of me for having a teaspoon in there but they borrowed it an hour later.

The spring loaded extending cane lead to the most capers as I recall.

The skeleton keys have come in useful too.

I have a larger version of one of these, I'll have to find it & post.

Edit: Couldn't believe my luck, wrote this, went out to my shed, checked 5 boxes & found mine. I've had this for 25+ years & not used it.
