The group doesn't usually issue multiple call signs for individuals, (gets all too confusing!), or allow multiple accounts.
I'm sure when our Admin team member Mr Gary Wilson next logs on and sees your posting he will do his very best to try and ascertain your original issued call sign number or account. (He's in charge of call sign numbers and issuing.)
Bear with him because he may need to ask you a few questions and if unsuccessful have to search through the old databases. He'll perform all that on a voluntary basis and it may take time so please show him some patience.
I've had a quick look at the recent lists and could only find an 'Andy B' registered from Manchester but unsure if that would be you. I'm sure Gary will be able to help you further.
All the best,
