I swear I saw someone overseas say they were able to get the XS-116 because they weren't able to get the XC-116 and was a fairly recent post about it.... Maybe they can step in and steer you in the right direction...
ah ha found it XS-116 from Omega UK - Find by partnumber maybe that will work for you... crosses fingers
This might just work they have XC-116 too. haha but both out of stock. Will just order and wait for an ETA.
Thanks MrKrinkle. Can I just use the torching method to prepare it? Or will it be too hot?
