BTW my interest in these and other Pionier related models is that I served as an Engineer in the Army for 20 years. My Military Occupation Skill (MOS) was as a 12C which is the military bridging engineer.
Now if I could only find models of the 'B' material and 'D' material bridges. After all, one company has distributed a model of the Bailey Bridge used by the British and Americans.
Thanks for the above comments and sorry for the above lesson.
