Thanks Fellas,
It has been a labour of love indeed but besides a good cleaning and tucking a few heads, there wasn't really much to do.
For its 80 years, the set was still in very good condition. Most amazing is how well the wrap survived. Zero fading and hardly a scratch,...
The pedal, L-arms, hi-hats and cymbals are nice to display with the kit but are absolutely not suitable to play. I also wouldn't advice to bring the boxed in floor tom + basket to a gig. The bas drum and snare however are perfectly playable and actually sound pretty good.
Aaron, the bass is indeed a 26" and the only shell with standard size. The snare and tom are 12,5".
Every day, I'm founding out more info on the Marius Renatus brand. Once I collected some more peaces of the puzzle, I promise to post it on this great forum.
A good evening to y'all from a snow white and freezing Antwerp Belgium.
