I will have a look in the book and get back to you it talks a little on the various mines but is more about the sheer will power of these chaps delousing them I will see if I can find the mine pic on line with I think Syme delousing a magnetic caption reads, Photo's of actual mine taken at great risk? it gives some scale as to the size of the chute.
Understand that initially these were not fitted with impact fuses they were there to destroy and terrorize the populace which they did very well indeed......

Not a great pic but you get the drift on the size of the risers for the parachute in the background just how heavy the mine was exposed are the fuse etc
The other is a magnetic stuck in the mud what call bravery getting the fuse out of that thing when the blast kill radius was 400 yards which you had to cover in 17 seconds the time it took the fuse to run?
