I have noted in my files seeing 1607 @ Cardiff on the 28/12/73 fitted with ETH, now I think that would be a decent model, I am not an expert but were there many ETH pre TOPS Cl 47's? Two others I would love are D1959 WR region allocated in blue simply due to my birth year as per page 98 Sixies D&E V (Strathwood) or any pre TOPS Blue WR namer not sure but has there only ever been 1 version of this?, but for now I will settle for D1565 and hope someone once saw it on the Western region
