This is an extension of the thread 'Vintage Ray-Ban Expert' Here you can find the weight of vintage B&L sunglasses to further confirm their authenticity if you are a collector or owner. I guess a few rules need to be applied to keep the wolves at bay. Rule 1: Only Bausch & Lomb Ray-Ban sunglasses allowed. Sorry to all those Luxottica enthusiasts but if your names not down you're not coming in. Other B&L variants will be considered. Rule 2: Please make sure you have exhausted all possibilities that what you possess is authentic B&L. If you have doubts head over to Vintage Ray-Ban Expert for more help. Confirm and then you can add your weight here. Rule 3: When adding to the database please check that the model has not already been added. If it hasnt then please insert the following in this order as it will make it easier for people to locate in the search function: MODEL NUMBER (if it has one.......W1234) MODEL NAME (Aviator Tortuga, Wayfarer, Aviator GF 12K, etc) SIZE (if it has one......62[ ]14) LENS BRANDED (is it etched) WEIGHT Rule 4: All weights must be in grams please. If you insist in using Lbs and Oz please convert to grams and record also. Rule 5: If you have a weight that is dramatically different to one thats already in the database then say so as the original may be wrong. We can then look into it further and either correct the mistake or add the new weight with further evidence. Rule 6: Sorry to be tough but this is a database not a mothers meeting. So any questions, like "how much are these worth?" or "can someone help with more info about a pair I got from my dads, aunties, boyfriends dog" should be asked in the vintage ray ban expert thread Rule 7: Anything else that clogs up the thread unnecessarily will kindly asked to be removed. Being that not all things are created equally, a disclaimer should be inserted, whereby, the weights you see will be an approximation and will only give you an idea of what the weight should be. Remember this database is only for weights, so if you have doubts about the authenticity, which includes other signs, eg, correct etching or other marks and you're still not convinced, head over to the vintage ray ban expert and Im sure somebody would be kind enough to help you out. Other than whats been said already, we hope the following database serves you well and thanks for your input. It is appreciated.
