Thanks for posting the pictures, Ideally I want some NOS ones, although starting to realise that might be unrealistic. Also it’s filtering out the SD7s that were subject to a safety recall for a specific production period. Thanks again for taking the time to post.
Well, a bit of a departure from my original requirements, I managed to get hold of 2 pairs of these fabulous Avid 25s. I just hope my Royal Blue Zaskar can carry the colour contrast effectively, or Is it a step too far! Thanks for those who responded.
