Thanks. However it turns out that, not unexpectedly, the fuel filler on my mongrel of an Alpine is no longer the original.I saw this lonk on one of our SAOCA threads https://www.classicbritishspares.com/collections/triumph-gas-tank-parts/products/triumph-chrome-vented-gas-cap-dome-83-3875-genuine-ceandess-29-7898-petrol-fuel
Looks to be the same (Triumph motorcycle), but, I'm not certain.
Something went off the wrong direction when I tried the link. I can highlight it and copy/paste into internet search to find the CBS motorcycle link.
