CARD Ballistic Pendulum.

[Mobiasstrip]

I got £25 for mine at the Nov 23 Wallis and Wallis auction. I paid 10 times that about 15 years ago.
Think they are now just a curiosity with very little value to modern airgunners …

Don't remember how much I paid for mine, over 20 years ago.. it is amazing how prices come to reach their peak and then go down. Numbers made could be the main factor. The serial number of 170 on my pendulum, gave me some confidence and feeling that it would one day be collectable
I have been given a lot food for thought
