Replacing Moulded Details

One of the things that now often puts me off buying ready to run models is the inclusion of moulded details. While I understand that fitting details by hand to a model would raise the price above what was economically viable, I think they nearly always ruin the look of what may otherwise be a fine model. On Skarloey there are lots of moulded details; in fact I don't think there is a single detail which isn't moulded. Given I don't have to worry about damaging the paint finish etc. I've decided to really go to town and replace many if not all of the moulded details.

So far I've removed the following details from the model; rear lamp, rear lamp brackets, blower pipe, cab handrails, drivers side boiler handrail, the number plate on the cab rear, and a small disc like feature from the cab rear the function of which I'm at a loss to explain.

Of those details so far I've only replaced the blower pipe and cab handrails but already I think that dramatically improves the model. Interestingly I didn't just have to replace the blower pipe but I've moved it from the firemans side (where it is currently on the prototype) to the drivers side where it was pre-preservation. This also raises the issue of which of the other details I need to add back. For example, the only old photo I've found showing the rear of the cab doesn't show any lamp brackets or a number plate, although a drawing I have shows one lamp bracket rather than the three currently fitted. I'll keep looking for more photos before I make any decisions but if anyone knows when the extra brackets etc. were added or any other info about such small details it would be great if you could leave a comment.
