I'll try to give you the best of my memory, don't have any literature. I think Scheeren was probably available about the time of Berlin Olympics. The rims if I'm correct were wood filled only, as I never saw any traditional hollow or ones with ferrules. There were two models, Standard or Weltmeister. The Standard was the heavier model,the Weltmeister about 270gms plus or minus. Don't have any more and don't recall. They came in drillings 20h-40h and sold into late '60's / '70s depending on inventories. Scheeren was the family name in Berlin and after the war as the folks got older they sold the tooling to Weinmann sometime in he late '50s I think. Weinmann sorta stuck the machines on the side and then came back with the rims I think in '66 in time for the World's in Frankfurt and The Nurburg Ring. Track and Road respectively. The Scheerens had little blocks of wood at the nipple holes to fill out the inside of the rim and thus reenforce the aluminum so the nipple wouldn't pull thru. Before the tire was adhered it was necessary to file the nipple head down so it wouldn't wear thru the basetape and cut the sewup stitching and let the tire blow out thru the bottom. This could present a problem if the nipple was filed down too much and left one or two sharp edges so that when spokes were touched up to true the wheel the sharp edge could be in the wrong angle and thenslowly cut thru the tire base.
   Most tires were hard shellaced with orange shellac and a bed of coats was built up of sucessive layers applied and dried a day at a time so that the initial glueing took almost a week. When done correctly one could usually pull a tire of carefully fix a puncture or replace a tire while leaving the bed intact. A thin coat allowed to get partially dry and very sticky was the prep needed before glueing the tire back on. We often could pull the tire off only about 5/6 inches, cut the tire open, fix the flat , restitch, and shellac the open area, pop the tire back in place, inflate to about 60/70 pounds, leave sit overnite and ride it the next day. If you were in a hurry, the guys would wrinkle up newspaper, start it on fire to accelerate the stickiness and drying process, put the tire on and be able to ride it much sooner. They did this in the auditoriums during the six-day races with the crowd in the stadium. Can you imagine lighting a fire during a sporting event today?! One saving grace is that if the shellac bed was thick enough it often protected the tire form the sharp nipple edge. We brewed our own shellac from flakes. Fast forward to '66, Weinmann made wood filled and regular non-ferruled rims at the time for several years and were used on Paramounts as well as many other factories. We also used double sided tape in the '50's, but that went out when mastiche gutta got betta for the bedda. Now it's making a comeback! Tufo is tuff. Oh yeah, Scheeren also made bars and stems, Probably post WW2 don't remember any in my dad's shop during the war or right after. Suspect around '48/49. I also have a set, and were mostly used on road. The bars are square road shape like Maes, but lots of road riders and some track guys liked the square shape on the track for the long hours and maybe more comfort.The German Diamant bike of Chemnitz had a stem prewar that looked just like the Scheeren but I don't know if Scheeren made it for them in the '30's or made them on their own after the war but patterned them on the Diamant prewar one. The original Diamant ones didn't have the best metallurgy or design or a combo of both and I remember the guys breaking them and then junking them probably to make P-40's. Maybe one of our German CR members has more precise details and will correct or share. Anyone else please add too. There is not too much info around anymore on some of this stuff Ted Ernst .
