Cloth Measuring Tapes
Those of us who need to use cloth measuring tapes know their value, especially ones that have a good return mechanism (specifically where you can defeat the ratcheting mechanism with ease).
I've used a German brand, but they have been very hard to find in the UK and in North America. In fact, for two years, impossible to find!
Just found the exact ones at Lee Valley Tools - on line as well as in at least their Ottawa store.
The stock number is 45X1818, and the cost is about $3.50 each. Great tapes for flight test purposes and strongly recommended.
