Seem to remember a batch of 2LW's were built in the mid 90's to service an order to replace worn out ones in South African mining loco's. A few UK orders were tagged onto this. Remember viewing a 1995 high spec nb built with a new one.
...just as the official end of production for Gardner LWs was about 1973, but there are examples around built in the 1990s (I think that the very last 2LW was outshopped in 2000). After all, if a customer is waving money about and you've got the parts, moulds etc. in stock, it would be silly to turn him away.
