This must indeed be from the early days of Transrol, before they added the second "L" to the company name in about 1981 (they told me back then that they had to do that since everybody spelled it that way anyway - the customer is always right).

Appears to be one of a pair built by T. van Duijvendijk, Lekkerkerk.

There appears to be a temporary accommodation on the deck behind the lifeboat.

Hello Frafo,
Very difficult, the position of the lifeboat eliminate the Saint Christophe and her sister.

Hello Edson,

It is similar to the De Biesbosch built SAINT CHRISTOPHE (IMO 7206859) but not exactly, maybe a sister. CORRAL on the right existed 1980 until 1991.
Greetings Frafo
