Since our original facebook page was hacked we were never able to recover the ability to login no matter what we did so we gave up on it. Since then facebook has upgraded its security with 2FA so it is harder for hackers to do this.
Anyway, rather than keep hitting our heads against a brickwall trying to recover the unrecoverable I have created a new facebook page at https://www.facebook.com/NewAnalogPrecision
And for those playing along at home the old facebook page is still accessible ;)
