26mm Rolex Spring Bars

[rmcsherry]

I just wondered if anybody has any information on 26mm Rolex single shoulder spring bars as used in Panerai 6152's? I can't even find a picture of one - I know they're impossible to get hold of, but surely photos exist?! I was curious whether River's spring bars could be adapted (ie. using 2 bars to make one with solid ends) to give the same effect as the original spring bars. Any help would be greatly appreciated.
