Music Man RD-50 top

Obviously the RD-50 also came as a "piggyback" top - as I learned recently through this ad in Germany https://www.kleinanzeigen.de/s-anzeige/music-man-50-rd-git-tubeamp-box/…
The model chart should be completed with this model variation! While the technical data might be the same as the combo models: Does anybody know anything about the weight?
