Sourcing Ashdown or similar grille cloth

[Soledad]

Can anyone help - I'm 'knocking up' a 2 x 10 to use as ext cab for a newly acquired Ashdown Studio 210. I've got everything I need coming (from Blue Aran, vinyl covering from Amazon). Ive checked Blue Aran, Penn Elcom, eBay etc but I'm stuck. Ideally I'd really like to match the silver cloth on the Ashdown (see pic as a reminder).

Don't want to spend silly money on this but it should look quite smart so I won't be too mean.

So far I got 2 Eminence ferrite unused £50, sheet material from stock, about £24 on all the bits from Blue Aran, including a pre-wired speakon in/out plate - so that was incredibly reasonable.

Any advice / help appreciated.
