I was down in father in laws basement and he has these just sitting there. The bad thing he does know what he has or is willing to come of them.
Now is the time to sabotage any brother-in-laws you may have. Become the favorite. Hopefully you haven't already blown that by marrying his darling baby girl when you're not good enough for her.
Even if they are all grown up and moved out and have children of their own, Name all of them after him!!!!
The only brother in law I have isn't interested in ole relics like that. And I have stayed on the good graces of the father in law. He knows I'm into vintage razors I just hope I'm at the top of his list when it's time.
And make sure every birthday and xmas present to the brother-in-laws are canned gel and catridge razors.
