Vintage Oxygen / Acetylene / Welding Cylinder Bottle Tank Steel Cap 3" Threaded

IF YOU ARE INTO STEAMPUNK ART, THIS MAY BE OF INTEREST!  The photos show everything. Not sure the age of this, obviously fairly old, vintage. I just don't know how old it actually is. This auction is for ONE CAP, similar to what you see in the first photo. I have eight of these available, the last photo shows all eight. You are buying ONE CAP. I don't know a lot about these, the threaded opening is 3 inches inside diameter, as best as I can measure. You can see words/ letters/ numbers on the top of the cap. All eight available have the exact same words/ letters/numbers. Each one is identical, some may display a little bit more rust than others. I am assuming whoever purchases these would likely refurbish/repaint, that is my assumption. Be sure you are comfortable with the condition, there are no returns. The cap weighs 2 lb. The shipping for these is the bulk of the cost. The more you buy, the better deal I can offer. Offers will be considered based on a zip code.  Please use the zoom feature and ask any questions you may have. THESE WILL SHIP USING UPS, FEDEX OR USPS, WHICHEVER I SELECT AT TIME OF SHIPPING.
