My grandfather was a sailor with the Royal Navy (I always thought he was a Merchant Seaman, but he recently corrected me) during WWII.
He was on the landing craft(not a very safe job I have heard nearly all his old friends got killed so my grandmother tells me), he won't tell me any more than that !! I don't know why, maybe he thinks he's still not supposed to.
He did tell me that he offered his straight razor using father and other relatives razors cheap as they were sold by the RN stores.
He still uses Old Spice
