As I thought, Berghaus have erased this 'incident' from their memory banks.................................................could also be that the person who answered doesn't know spit
I can catagorically tell you, as no doubt many others could, that this is not a cyclops roc but a early PLCE shortback bergen made by Berghaus.
At least they answered your email.................thanks for the update.
To be fair to Berghaus they are focused on selling the current product range and providing reasonable support for the older products.
An email to customer services over the Xmas / New year period is not likely to really give you the best result and IME the folks in Berghaus CS do not know a great deal about the older product.. Which when you think about it is reasonable enough. Berghaus as a company today is totally different to Bergahaus 20 years ago.
My thoughts is the Bergen in question is likely to be a bit of Trials Kit. The MOD ran some extensive trials on different PLCE type Kit prior to the introduction of 90 patt PLCE (the green stuff). IIRC collectors call it 85 pattern although im not sure that is 100% correct. If you look around on the PLCE webbing thread there were some images of the trials type PLCE kit.

Any how a Berghaus Trials / PLCE Bergen is a rare bit of kit... Ebay will likely yeild the best results if it's listed and described correctly. Folk pay outrageous sums of cash for this type of stuff.
