Thanks Simon, there's a few tears/splits too, just hope I don't add to them, will use appropriate glue on them
The mechanic whose doing the work has a mobile sandblaster visiting to do a tractor he's also renovating ( tractors are huge over here, classic cars a poor second).
A previous owner thought he spice up the engine bay by chroming the air filter box. It's looking very sorry for itself so will get him to lightly blast it too!
NB. As per pic, note more newspaper pieces found inside the actual filter, those Portuguese mice will set up home anywhere!!
