What would shipping to the uk be, if you're willing?
I'm willing, but I'm not sure if it would be worth it. USPS is showing ~$50 USD for shipping, which seems pretty steep to me. If you can determine a cheaper way to ship the keyboard I don't have a problem sending internationally, or paying ~10 of the shipping.
Out of curiosity, where did the coiled cable come from?
They came from some older Cherry keyboards with MY switches, some with doubleshot keycaps. You can just remove the pins from the connector on the Filco and put the cherry cable in, although it doesn't route perfectly through the housing of the case.
