Bahco used to be one of Europes largest tool brands, and may still be, and they had tools produced in a number of different countries, including Sweden, France, Germany, Spain, Enland/Uk, Portugal, probably Italy, Argentina, and probably Japan, USA, Canada, Russia, China, Taiwan, etc.
after Snap-On bought Bahco and made them Snap-On Europe, they shifted a bunch of production from Sweden and Germany, to Spain and France, and other production to Russia, but a bunch of the tools are still the same and produced in the same countries they were.
Even the French and Spanish made stuff is good, although not as highly regarded as the original Swedish production.
As far as OPs question about the pass thru ratchet.
Most of that style of ratchet are currently imports from China or Taiwan, no matter what brand they’re sold under.
The brands sometimes have different handle styles made for them, as well as variations in the socket mounting design, but there are two main types now. The hex shank sockets, that have an outside hex design on the retaining end of the socket, and an external spline grooved outside on the retaining end of the sockets.
The hex designs usually come in three different mounting sizes, which are used to make the sockets equivalent to traditional 1/4”, 3/8”, and 1/2” socket sizes, although there are variations in how the sockets lock into the ratchets.
The spline designs use the same size variations as the above for there mounting system.
I believe the spline design may belong to Apex or Danagher or whatever Gearwrench and there owner is calked nowadays.
The hex design gas shown up on Lowes Kobalt amongst other brands.
