Just added my third 48oz to the collection.
Looked for a few years trying to find one instead of ordering one then went ahead and got one(Vaughan) on Amazon. Immediately after I found the Stanley on the left and this week I got the New Britain in the centre which I've polished up a bit and painted the non-contact surfaces black as well as a touch of white in the lettering.
Also wedge is interesting, haven't seen such a robust wedge on a hammer like this. It's usually the traditional or maybe the O ring style but this kind I think I've only seen in some sledgehammers.
Not mint condition but faces are clean and it's ready to work.
