Hi... Write directly to me at trainman@traincity.com with the auction number and I will do my best to get you feedback.
You probably talked to John who I am sure knows what track fluid is. I'm not sure of the nature of your question if you just wanted track fluid or you specifically wanted track full fluid containers for the 3927. That would be a tougher request but we don't handle parts or supplies on a regular basis. What I would do if I were you would be to google 'track fluid' or '3927 track fluid containers' and something will pop up I'm sure.
The unit came with both fluid containers, I just want to know where or how to purchase some fluid to put on the pads. I did find some on the internet but $9.99 plus shipping charges seems to be a bit MUCH for 8 ounces.
