Buck Collection Growing and Question

[BRKCOP]

Well I have been on a kick lately in finding older folders in the 500, 501, 503, 505 and 506 series. All script logos. Maybe someone can help me regarding the top 501 that has 3 rivets and all the others are 2 rivet. I am not familiar with this one as all the others are two rivet. ???

The exposed rocker rivet was found on the earliest version of the 501. This thread explains it well.

Sweet. Thank you for that information.

BRK, a nice collection. I see you like the 500 series. The last of that series to have the the old English script stamp was the 507 Ultima.
It is quite handsome with mother of pearl handles & polished blade & frame. They are in the display on the right, lower middle. DM
