Exact size of the compressor crowns on 1964 Sherpa Jet MKI?


New member
Hello - yes, I got bit by the Enicar bug over the past couple of years, living in the foothills of the Himalayas helped.

I have an early MK 1 Sherpa Jet that has an incorrect crown - I see several available on eBay and elsewhere - but what is the correct size of these?

My Sherpa Jet Mk2 (148-35-02) crowns are cross hatched with a Diameter 6.3mm x Length 4.1mm

The crowns look shorter on Mk1s when viewing images online, maybe 6.3mm x 3.1mm?
