Hello
You will find the know it all idiots / trouble makers(keyboard Warriors) where ever you go... you've got to just try to rise above it... and its not always easy.
To be honest, anyone who helps value stuff or identify things should be doing it for the love of the hobby... I sometimes sell stuff fon behalf of other people and then get a cut.. but not just for helping out with a bit of info.
Anyway, the problem with old VW parts is that some will think they are worth a lot more or less than others... there is no correct answer.. the only real way to find a true value is a full decent description and using ebay ... but not everyone is an ebay fan.
you are welcome to email me some pictures and i'll try to help with identity ... but remember if I see something I need... I'll tell you its worth £1
:d
