Although it does not indicate the country of destination, many of the
following 1300 & 1600 engines were installed in breadloafs (Sometimes it pays
to keep the old parts catalogs and very outdated fiche films):

1300 Engines:  Series AB Case 71-73, Series AR Case 74-75 (Talk about
UNDERPOWERED!)

1600 Engines after 1971:  Series AF Case 72-73, Series AR Case (Low Comp
Pistons) 72-79, Series AS Case 74-79

Note:  All were Dual Oil Relief Piston Cases and Dual Port Cylinder Heads.
 I've seen a lot of rebuilt engines from various suppliers using the "AB"
Case from engines brought in from Europe - normally upgraded here to 1600.
