A nice original Minerva handbook for the 20hp AE and 30hp SF models. It’s in good complete condition with no loose pages. It has English text. I accept PayPal and will post worldwide at cost.
This is the small coupling to go onto the magneto where a two prong drive is used, like early Delage. It fits any standard magneto shaft and the nut is concealed in the main part. There also the special part used to tighten up the special nut.It's been on my shelf for years and I'm having a clear out!
