I bought a short yellow band years ago, did'nt get a good feeling about it so I asked around and Bob Hirtz told me they were original and found on rolls and cut and sold. On this point I would say we all know that a full lenth of any cuff title sells for a lot more that a cut version of same and they were well aware of that in the 80's, so I think it is safe to assume that the short ones must have been woven with not much of a gap between the lettering, hence they are all short.. more titles per inch of material.
My red title breaksdown to 114mm left of lettering, 62mm of lettering then another 163mm right of the lettering, giving 339mm.
My yellow short one breaks down to 26mm left of lettering, 92mm of lettering and another 28mm behind it.. total is 146mm.
Now I hope this makes sense, on the roll, there must have been a gap of at least 277mm between the individual letterings on the red full lenth cuff roll (114 + 163). On the yellow roll it would be 54mm between the titles (26 + 28)
I can also say that the red lettering is different (thinner) on the full lenth red one, and the "=" seems more square, the yellow "=" appears to be slightly slanting upwards and as mentioned the full lenth one is softer and feels to the touch more period.
I have tried a burn test on the black material, for me the red passes and the yellow fails. Others can try it and see what they find.
Ken Jasper once beat me to a green title on one of Detlev's updates, must have been a good 10 years ago, maybe even more, it came with docs of entitlement to wear it and other pieces, very annoying but at least it went to a good home, From memory it was shorter than the full lenth red one, but longer by a fair bit than the often seen short ones, I had pics of that group from the update but that computer was stolen...anyone else save it? Long time ago, but reference files are there to be kept so maybe?
The Berlin triangle is there for scale only and did not come with my red title, which was bought as a single item from Detlev.
Pretty long winded, sorry.

p.s. I will edit to add that what Wim Saris has to say about the heavy faking of HJ triangles on the WW2 forum should dispel any hopes that HJ was'nt faked much in previous years.
