The grey one was converted to standard spec.
I sent Andy Haslam a photo of his twin at the factory and explained that sadly they converted it to a heavy old standard 4/4 as it didn't sell. He has been trying to register on TM images for yonks but all to no avail. He and I are on a shared Facebook Morgan members group.
Graham and another bloke J something or another (he kept on changing his handle) both worked as MMC guides at the time so the knowledge was accurate in those days and this pair are well documented on TM..
The previous owner of Tango was a professional skipper and had Henry black it out which works very well, he lived in the West Country too. Work got in the way but he used it and enjoyed it properly.year round as I recall from his postings on here.
