Agenoria O gauge
It's a pity the plug has been pulled on Agenoria O gauge range because they offered unique prototypes for modellers, something different and with endless opportunities for layouts.
I personally model nowadays in sixteen mm narrow gauge but dapple in other scales. I had intentions (funds allowing) of purchasing a couple of GWR absorbed tank locomotives from the range and starting in finescale O guage which now I can't do.
Even though there are ready to run O gauge locomotives entering the market many of the Agenoria locomotives will I doubt ever be produced in a ready to run format or again as kits.
