请教双城记中一句话的状语动词与主语动词发生时间先后的问题，谢谢大家！

The coach lumbered on again, with heavier wreaths of mist closing round it as it began the descent. The guard soon replaced his blunderbuss in his arm-chest, and, having looked to the rest of its contents, and having looked to the supplementary pistols that he wore in his belt, looked to a smaller chest beneath his seat, in which there were a few smith's tools, a couple of torches, and a tinder-box. For he was furnished with that completeness that if the coach-lamps had been blown and stormed out, which did occasionally happen, he had only to shut himself up inside, keep the flint and steel sparks well off the straw, and get a light with tolerable safety and ease (if he were lucky) in five minutes.

邮车又隆隆地前进，下坡时被更浓的雾像花环似地围住。卫士立即把大口径短抢放回了武器箱，然后看了看箱里的其它枪支，看了看皮带上挂的备用手枪，再看了看座位下的一个小箱子，那箱里有几把铁匠工具、两三个火炬和一个取火盒。他配备齐全，若是邮车的灯被风或风暴刮灭（那是常有的事），他只须钻进车厢，不让燧石砸出的火星落到铺草上，便能在五分钟之内轻轻松松点燃车灯，而且相当安全。

1 请教各位老师，描红的having looked此处是不是完成时做状语？如果不是状语那是其他什么成分？谢谢！

2 如果是完成时作状语，我觉得having looked这个动作应该发生在主语动作replace之前，但是我看了两个版本的翻译（如上所示），都认为look这个动作发生在replace之后，所以非常疑惑请教各位老师观点，如有完成时做状语的例子佐证最好，谢谢各位！
