@Pucciowitz correct, complete GF bracelet is about 1000€ which is for sure expensive but add "value" (not only financial but historical etc...) anyway to your A386 too.
Even if I do not find it very nice, i would definitely like to find one as for collection purpose.
They appear from time to time and was about to buy one few month ago but did not as it was dated 1971 while my A386 is 1969...
Now I can say I almost regret it quite a bit...
