Apart from mistyping 1 instead of 7 in my remark about Hermes (the single bedstead radar is difficult to reproduce but Triton Skytrex managed it) I stand by my remarks.
Fleetline and Skytrex Triton both made T42 and there are plenty of pictures courtesy of eBay etc to make comparisons. I have them in my collection. I do not have the Delphin model but it is very similar to the two Brit models.
As to whether I would buy the models or not. Not relevant. This is not your website and comments unless rude or libelous are permitted.
