Stockists of Guabello fabrics

[Odradek]

I had a thread on a related subject a few months ago.
Trying to buy a metre or two of fabric to match a suit I bought in early summer.

I've found from the suit manufacturer that the fabric is from an Italian company caled Guabello, and I have the code number.

Does anyone know if there is a stockist of Guabello in the UK?
The two big fabric dealers that I've called in London don't stock it.

Also, my wife is on trip to Boston this week. On the off change that she might pick some up there, does anyone know of a Guabello stockist in New England?

Thanks
