I have a dozen Montgomery 's. I plan on cleaning up and using or listing.
But I dont know the size? They are 5 1/4" inside measuring.

Super strong springs ...I wire brushed with dremel brass ...one pan on one of them just cannot read the # size???

If you know about these traps tell me or pm me. Thanks!

I'd say it's a #2 as Monty's ran small to size

I believe it is a 3 because 4 is 6 in side

Still confused

i'll check tomorrow, raining too hard to run out to the shop

I just cleaned up some of those yesterday they're #2s.

Thanks... !!

Look like the high lever model from here.

The pitted rust may make levers twist.

Swivel, adjust, and run em.

They are #2's

Put levers fm Bridger nbr twos on traps and you get a high lever trap with better holding trap. The low levers on original trap is why some trappers four coiled them as the low levers didnt have alot of holding power.

How can you tell if they are high levers??

Yeah?

8 sided vs 4 sided pan.
Show a pic of the lock up is the for sure way.

As I said, pitted levers get weak.

Back when no one liked or understood dogless,
I had 10 dozen.

And, the chain on those are superior to other swing set chain, unless rusted or beat.

330 then old traps are not good for any thing you might be trapping so just send em here and i'll put em to rest for ya

There's only rust...no pitting

I know they're too strong

Little known quirk.
2 5/8" wide pin = low
2 7/8" pin = high

"generally speaking"

I have a few of them

I sold mine in effort to standardize, then another nest of them reappear.
Most of mine were dogless.

Cotton, that roofer guy, Conner, and Graham know a lot about these.
When they spoke I listened.
Terry too.

I toured the manufacturing plant, it was a great experience.

That must have been Awesome
