Regarding Larry Myers cry for Cyclo Benelux rear derailleur adjusting help to shift into high gear on a five speed freewheel, the following are various adjustments I have done on different Benelux rear derailleurs to reach that outer cog more easily. I have copies of the Cyclo manual from Chuck Schmidt's Velo Retro and the instructions only take you so far.... they don't discuss bending, cursing, and knuckle banging, which are well-known bike mechanic tricks..
* make sure your Benelux rear derailleur is marked for five speed freewheels... not all are
* lube the rear derailleur well and work it by hand vigorously and repeatedly, hoping to limber the darn thing up
* bend the derailleur outward a bit to more so that it can more easily reach that outer cog, or put a washer into the hanger assembly to shift the derailleur outward a tad more (then you don't have to push quite as far and hard to shift into high gear). You may wish to remove the outer locknut to increase the horizontal range of the pulley cage (admittedly a desperate measure) so that the derailleur will still reach the inner cog after being shifted outboard by bending or a washer
* re-dish your rear wheel a bit to shift the freewheel inboard a bit more
* obtain another Benelux rear derailleur and try it
* give up and use a four speed freewheel. A real bike rider doesn't need a five speed freewheel for crying out loud. You don't need all those damn gears; you should be hammering at the pedals or looking at the scenery, not playing with your gears.
I'm not an expert so your esteemed mileage may vary.
