Transit, you are correct, this old preset works well up close and to Yeatzee's earlier point on the wisdom of primes and macro, they can/do work well on tubes.
Transit your post above prompted me to dig out my bellows (still have not gotten around to purchasing M42 tubes) and poke around my wife's garden tonight with the bellows and Takumar 135 preset hand held. Below are a two different compositions of the same flower.
The earlier post and photograph in this thread of the yellow columbine was with a 135mm fujinon enlarging lens on the same bellows - at a longer exposure and small aperture (a little sharper), so Spiderman there is hope for sharp macro on bellows if you have a tripod and some calm winds.
This is the image without extension on the 135.
