I think 19 is probably about right. Me and my dad were talking to him at GDSF last year and he's a really nice fella and willing to chat about his stuff. Ah yeah dolphins worth a pretty penny and with the new paint job she's had she's probably worth over £300k at least. Then its the same with Goliath one of his other showman's engines and the only McLaren one in the world. My dad was lucky enough to drive both of them when they were owned by Frank Lythgote who Mike brought them from along with a few more of his engines. I believe Frank now collects vintage tractors instead of traction engines.
