Rolling Wheels for IWC brand window

Hello,

We have seen similar rollers for IWC windows in the past and have not been able to locate an exact replacement. We'd be happy to research this further but we would need to see detailed photos from multiple angles. We'll also need you to write out the exact width and length of the top flange and bottom wheel housing, as well as the height. We will also need the diameter of the wheels. We can't make any guarantees but this information will allow us to confirm if a replacement is available. Thank you.
