Stihl FS 250R twins/FS 56R strimmer

These are my strimmers,a pair of FS 250Rs and an FS 56R. The 250R in the middle came without decals,paid 200€ for each of the twins and about 100ish € for the 56R.The newest strimmer was built in 2009,which I think was the last year of manufacture for these loop-handled beauties.
The camera I use is a GoPro 4 Silver
