I’m a joiner and make a lot of bespoke doors. I don’t know what you mean by ’style’. That is an old slower grown pine rail and stile door with a raised panel and maybe an applied moulding (or more probably a scribe cut). You would be incredibly lucky to find one exactly like it - with the same moulding details and raised panel details - as there is no standardisation for spindle cutters or moulding planes etc. That is, different producers produce slightly different doors. If you bought this door to my workshop and asked for exactly the same door I would give you two prices. One to make you as similar a door as I can with the panel raisers/scribe cutters that I have - this door would be so similar that only a careful comparison could tell them apart - and a second to make the an exact match; with the second price being significantly higher than the first.

Having said all that, if your door is a standard size there are plenty on new solid timber raised panel doors around for sale.B&Q do a 4 and a 6 panel door that is pretty close that is only £64: but don’t order by delivery go there yourself and get a straight one. This won’t be as close a match as someone like I would make you bit the price is only a fraction of a custom made door.
