Looking through the emails in the TR account I believe these were agreed based on Becky's minutes sent around on 23rd March 2016:
"8. Constitution being changed to allow one signature rather than two for payments (this allows treasurer to pay in at the post office and for charges to be paid easier) Sue to send draft of this to be confirmed at next practice."
I think based on the items highlighted in red those handwritten notes must refer to the changes - which include the changing of signatory to any of rather than 2 of, changes EGM notice period to 2 weeks and allows for anyone rather than 2 people to sign stuff.
There is then another email from Becky which states that as no one had commented on the changes any further by 26th April 206 that Sue could go ahead and make the amendments. Therefore the latest one is the one entitled suggested amendments, unless you modified this further Sue so as to not have the red text?
I'm assuming that as you say that you never did acquire a bank card, which I believe was the key driver for this, that perhaps that is indeed the latest one.
I guess my only question following on from this, is is there a requirement for the positions listed as officers to be signatories? Or do the bank not actually mind and just want three committee people? Just thinking that the signed version is you Ffion and Becky which at the time would have been treasurer, foreperson and secretary. Not that I want to cause extra hassle in sorting out this paperwork, nor am I in a rush to be put down as a signatory. Alternatively, do we need to amend our constitution to list all the other officer roles? (This has to be done at an AGM/EGM apparently, so for speeds sake, would be good to figure out by tomorrow evening so we can get Emma as a signatory asap, hopefully without jumping through too many hoops.)
Apologies if none of this is relevant, I don't know the ins and outs, so am just going to ask a hoard of questions that hopefully someone knows the answer to...
