These drums are very dirty and the marks are rather indistinct. The Chief Officer has traced these drums from the boat notes. They belong to B/L No. 37.

这些桶很脏，并且标志极不清楚。大副从驳船装货清单上查了一下这些桶，它们属于37号提单。

There are two B/L NO. , the main one is a single customs declaration number, and the other should be addressed to the foreign customer.

提单号有两个，一个是报关的主单号，一个是应该给国外客户的。
