Well as we don’t have the dia, length and thickness of the boiler yet its a bit hard to say , Also we don’t know what size the original was, a small 2hp engine will have a smaller boiler than a 8hp. I have seen a picture of the back end of this portable next to a 2″ Fowler and would say the boiler dia is 3 1/2 to 4″ dia, and maybe 6″ back wheels
Based on my 2″ Fowler that I had made about 3 years ago and the fact copper prices and VAT have gone up I would say £1000-1500. Depending on whether you go for silversoldered or TIG welded copper.
