Yes definitely looks like chain roller shells. Full strip down required.
Barrel piston and head too... Or just the chaincase?
no not top end just chain case.
If it were me though I’d strip everything out including the gearbox and clutch and wash all the components and swill the whole inside with paraffin.
Have a good look at your chain, is it made by Rolon by any chance? If it is they are shite and should not be used, go for something decent like Regina for around £30 or if you must an Iwis for around £40.

Update.. Casing off.. Think iv found the problem.. Think its a rolon chain.. Can't make it out.. But looks stamped on every link.. And one of the roller covers?? Is thinner than the rest.. Looks like that's the culprit..?
Now.. What link is the chain.. Is it easy to come off.. Anything else I can do simply whilst in here... And when putting new gasket on.. Just straight on? (lambretta upgrade thicker gasket) hope the pics are OK..

Now.. How do you determine what link is the chain.. 80.81...82...Is it easy to come off.. Anything else I can do simply whilst in here... The 3 broken pieces fit to make a perfect cylinder.. Don't think I will be looking for any other debris...??? And when putting new gasket on.. Just straight on? (lambretta upgrade thicker gasket) hope the pics are OK..

Put a thin smear of grease on both sides of the gasket when rebuilding. Yes definitely a rolon chain.
