The way the "knuckle" locks and unlocks would be challenging. I'm sure it could be done - after all, Brian Banna scalled down the Sergent coupler into an operating N-scale of similar

So does that mean if I got you a prototype coupler.... Just kidding. Thanks for the reply. Expect to see some of your knuckle couplers appearing on model Russian stock before too long. Matt

Hi Matthew, An SA-3 is just too far out of the comfort zone for us to consider making. Not only am I not familiar with the models, I'm equally unfamiliar with the prototype. Sorry. Thanks, Frank

Ron, You are right the name could use to be more accurate. But "The Soviet Union, States Formerly or Currently Under the Sphere of Russian Influence Modelers Collective"was a bit long. Typically those

Matthew, Wouldn't this group be more correctly named Soviet Modelers, as in USSR/CCCP, not Russian? Or, if you're modeling prior to the collapse of the Soviet Union, are you sticking only to the

Yes, that's the way to go. Make sure you get the assembly fixture to build your couplers, they go together very easy, I usually build enough for 10 cars at once and many times I've sat at a truckstop

Dale, thanks for the information. That is what I thought, but I was not sure. I guess it is time to order a bulk pack and start assembling them. Paul

Hi Paul, you don't need extended shank couplers with Sergents because there are no trip pins to worry about, with Kadee for example if you had a plow on a loco you'd need an extended shank so the trip

Frank. not Fred. Sorry!! I meant Frank. I got as far as FR and my fingers wandered from my brain. I'm sorry about that. Matthew Picciotto

I wrote to Sergent but I guess my email bounced. Seems to be a problem I'm having lately with a lot of websites. I saw that Fred is on here so I thought I'd just ask here. I was wondering about the

Hi Guys, After having purchased one package of assembled and one package of kit E87 couplers, and running a train with them for a few days, I have decided to change over to them. The standard ones

Thanks Frank. I'll move on.

Hi Rex, I only ask as on the Sergent's website they mention it's used in the production of their couplers to get the rust brown colour. Regards Daryl

California just needs to get over themselves, the air they breathe can b toxic too, but you cant outlaw breathing. >_>

Hexavalent Chromium was the main topic of poisoning discussed in the movie "Erin Brockovich". PG&E, (Pacific Gas and Electric) once used it in some cleaning process in Natural Gas Production. After

Hi group, The plating that we used to use to get the nice rusty brown color on the couplers contained hexavalent chromium, which is known to the state of California to be a bad stuff. There is an

Thank you Duncan. Very to the point and clearly thought out answers.

I searched this Sergent Yahoo list, the NCE-DCC Yahoo list, and the Digitrax Yahoo list. The term Hexavalent Chromium was found only once and that on the Digitrax Yahoo list. The discussion was

Hi, I'm a newbie as far as Sergent's couplers are concerned and as my new layout will be timetable and operations based with lots of switching I'm looking for an alternative to Kadees that operate

I had forgotten the main reason I made my first post was to indicate that although I was familiar with the outward appearance of the Tomlinson coupler and how they coupled I never understood how the
