Parker Knoll chair seat repair kit (HR1 Tupsley)

Unused set of tapes and springs for replacing worn out seat of a Parker Knoll easy chair. Reference number is apparently PK936. We bought two sets in 1980 and still have the repaired chair; 3rd photo shows the springs in place. The long ones are 439mm, medium 422mm, short 399m with about 7mm extra at each end for the hooks; about 10mm longer in place. There are 16 new springs and 3old ones which may be easier to fit. There are 10 eyelets so quite a bit of flexibility.
