Nothing to be guilty about. Ireland’s finest railway  

And, of course, modellers of the NCC area in UTA and early NIR days can find room for Lough Erne and Lough Melvin…

Right then, not so good news having asked Kirlty about these locos, but it appears that the method used by Tony does not allow him to mass produce them, so I think if we are going to get them in kit form, I need to search out all the possible drawing's I can find and then ask Allen what he thinks?

Is Tony's method based on hand-drawn artwork rather than CAD?

As I understand it, yes it is, I was also told that he had to do three or four sets of etches to get enough good etchs for Kirley to build just the one loco.

I did email Allen (Worsley works) and his answer was to find him the drawings and he will see what he can do

Did he keep the reject etches? There might be enough viable parts in them to create one or two more sets....

It looks like Tony may have etched the parts for the SLNCR tank using a 'home etch kit" available from electronic hobby stores.

Using these kits the unser prints their design of a selfadhesive resist film using a photocopier or laser printer. 

It might be worth asking Tony & Kieran if they are willing for Alan or a business like PPD to check whether the existing artwork is suitable for producing a phototool.  

Tony's chassis/running plate artwork appears ok.

Main potential issues I can see is that the artwork in the photo does not appear to follow the colour conventions used by commercial photo engravers and the narrow width of the artwork.  Ideally the artwork shoud be drawn 290mm wide with the loco underframe and substructure on a single sheet, I would recommend 0.4mm nickle silver for strength and stability where the underframe and superstrructure are etched from the one sheet.

PPD Artwork Guide summarises industry conventions https://ppdltd.com/artwork-guide.html PPD have a 1 off set up charge for preparing a Phototool from the artwork and will print a single or multiple sheets at a fixed rate per sheet.
