Anybody know how to tell them apart? Can’t find any lettering.

Exact inside jaw measurement would help rule a lot of brands out, in my experience.

If they are certified under the international standards the dog will have a 3 letter identification stamp.

Boco you kill me!!!

Most of them say something on the side of the dog to ID them. See what yours say and post it here someone will know.

Post the stamp like ADC said and I will identify it for you from the sheet.
Dukes may be on the rivet and sauvageau on the jaw.

Found them. Used a wire wheel and there they were. Thanks all

Some of the ways to determine body trap brands besides the stamping on the dog -

Shape and style of trigger.
Stamping on top of the bracket holding the trigger wire - BMI traps were stamped there as were Montgomery killer (MTI)
Shape of the jaws - early Master Killer and early Northwoods
Type and position of the jaw rivets

The 3 letter identification stamp only applies to traps sold in Canada. Boco some times forgets that not all Tman members are Canadian.

I Didn't know that wissmiss.I figured that might be the case with foreign made traps like duke but I figured all Canadian made traps would have the identification stamps no matter where they were sold.Is that the case with the European made certified traps also?.

Boco, you also have to remember that many traps existed before the certification that do not have the 3 letter code.

That is a good point,but I think professional trappers retired those old traps a long time ago,at least if you want good fur.Might be a few around for nuisance work where pelts are discarded and there is a chance of theft.

There are any number - probably thousands - of various brands of body traps that were made before the Canadian standards went into effect that are still in use today. And they are catching fur just like they were in the past.

Conibear by Animal Trap Company
Blake & Lamb
Herters
Montgomery
Northwoods
Master Killer
to name a few

Trappers in the US didn't just discard (throw out) those traps simply because of some standards that Canada said Canadians had to follow. Throwing out those traps would be like throwing out a perfectly good pair of shoes simply because they are no longer "in fashion". Just plain dumb.

Canada and the United States have some things in common. But when it comes to the fur industry, there are several major differences. And when Canadians try to tell Americans how things should be done, it simply points out how little Canadians know about the fur business in the US.

Just saying.

I upgrade my tools of the trade on a regular basis,nothing to do with the trap standards.And so do all the professional fur managers I know.Upgrading tools in this industry means a better product.Weak worn out traps have no use on any responsible fur managers trapline.
Also as better more efficient and more humane tools are developed we upgrade.
One good example would be the new quick killing snare systems that have been recently developed.They have been embraced by professional fur harvesters on both sides of the border because they are a better tool producing a better product.Snares do not fall under the aihts agreement here but most trappers are smart enough to know it is only good business to use the best tools available.Another good example would be the old series 1 conibear traps,a terrible trap for causing fur damage,but still legal under the aihts.I know of no trappers here using those traps for fur,but there are some used for nuisance where bears or theft may be a problem.
Nothing to do with regulations as many traps replaced are still legal,just not the best tools for the job.
As you say
Just sayin.

Holy cow!!!!!

^^^??
