This is a livestock drench gun. It was made by Syrvet and I do not see a model number on it. This item is in used condition, with wear like grime and dirt etc. Useful item for farmers. Terms of Sale: Read before buying. Make sure you are bidding on what the item ACTUALLY IS instead of what YOU THINK IT IS. 99% of the items I sell are in used condition. All sales are final, so please do not bid if you are not going to pay for your items. I am no longer offering returns. Shipping: Items are shipped within 24 hours of payment being received. If payment is not received within one week of the auction’s end, I reserve the right to cancel, relist the item and report you to ebay. I do offer combined shipping for multiple items, but please ask me about it as I don’t always catch that people are bidding on multiple listings. I do not ship internationally. Feedback: I leave feedback after it is left for me. If you are unhappy with your order, contact me before you leave feedback and I will do my best to work it out with you. If you leave feedback first, you forfeit that right. Please take a look at my other auctions and happy bidding!
