I blame you for the uncomfortable image of Anne nipping round to give a housebound Tony some rejuvenating how's yer father, in between Mike popping in with bottles of Bristol Cream and Tales From Liverpool for his invalid pal. 
The evidence is that it was Mike who made the initial enquiry. And who can claim to know the mysteries of a mind like his - apart perhaps from his wife, who'd have been certifiably insane to get herself involved in a forgery project with such a man.
The long delay would be explained by Anne's total ignorance of Mike's enquiry - until it had produced a tiny Victorian appointments diary for 1891 and a bill for £25 which Mike failed to pay, marking him down - Mike, not Anne - as a late payer. He finally asked her for a cheque [I'm not sure Mike yet had a bank account in his own name], which she was not happy about. She signed one and threw it across the room for him to fill in the details.
I suspect you are right about her not wanting to be involved. But she gave herself little choice if she was committed to this crazy diary scheme to implicate Mike, despite her lover's fatal heart attack, no doubt brought on by too much of the other.
Love,
Caroline

Bottom line: someone in Goldie Street went shopping for blank Victorian paper. Of that we are certain. Only a very limited number of scenarios can explain why. If Anne had paid the bill on-time I'd be more confident about her complicity; that there was a long delay suggests she didn't want to be involved.
