Have some tube type with nipples waterers for sale. Two of them are all put together and have been used- 3 of them were never put together. Have most of the parts for those 3-but I know I used some nipples, etc from them for replacements on the others. I do have the regulators for sure for those 3. I think they are the ziggity brand, model 1000. Sold as is. They sell for about $90 apiece new, I think. $200 for all of them!
Please see pictures for details. Ask if you have questions. I also have some other waterers, a brooder heater, some catch nets and a bunch of wooden chukar crates for sale.
Thanks for looking!
