Hope you got my email reply to you of a few days ago with the same questions?
1 - Accurascale was born out of Irish Railway Models, an Irish company established over 5 years ago. Accurascale Ltd became an English company in October of last year as part of our Brexit preparations. Since launching on the UK we’ve delivered the HUO wagon range in two scales, the PCV Cemflo, the PCA tankers, the PFA wagon lines and in the next 4 weeks our PTA and JSA ranges will be in stock. Additionally we’ve shown samples of the 55, 92, KUA and soon mk5 coaches and have many projects underway as yet unannounced)
Our warehouse and distribution is in Peterborough and we have stockists throughout the UK and Ireland - https://accurascale.co.uk/pages/store-locator
2 - We hope so Our ethos is to deliver models that are 'definitive' to the prototype and as detailed as possible (even the parts you can't see) at the most reasonable price we can achieve.
3 - Per my reply, the photos on the site are of the Engineering Prototype of the KUA - you can see how it will be painted and finished in this image:
4 - As per this thread, the Fully decorated samples are due week of the 7th September, with assembly proceeding directly from then, all going well they should be in hand before year end.
