Bob is correct. That is a Kirk DeKalb trap. I have one of them that I bought from Kirk at a SE regional convention years ago. It has the conibear style trigger mechanism that he also used on some of his other cage traps. It is longer and heavier than other brand tube traps on the market and that may be an advantage as described in the video but it is also a disadvantage as it requires a much larger CO2 chamber.
I remember Kirk selling the manufacturing rights to the company in Canada but I do not think they ever produced many traps. Cost seemed to be more than the market would bear. Not sure what the current status of Kirk's designs today. I just know that I have not seen another tube trap like the one in the video other than the one I have in years.
I also have one of his swim through beaver cage traps with the conibear style trigger. Trap is heavy and works great but I have only stumbled on to one other one like it at a convention. Kirk had some good designs and built them heavy duty but they were not inexpensive to manufacture or ship. Couple that with his health issues that limited his ability to market his products at conventions is probably why they are not more prevalent.
