The creation of a protectorate is convenient for the superior and the inferior; it relieves the former from the full responsibilities incident to annexation; it spares to some extent the feelings of the latter.
I decided to install a fully reconditioned 1950 cc. engine from MGOC Spares, fitted with the unleaded cylinder head.
Interestingly, it was left remarkably intact, whilst the other locos in the line were heavily robbed of spares.
On the plus side the batteries are tiny AAA cells so carrying spares is less of a burden.
Members wishing to buy or sell spares may advertize free of charge and the magazine also carries trade advertisements relevant to Ariels.
