Can someone please explain to me if this pressure nipple could of been pushed in or hit. It sits very very low compared to my other 15 PorkPie Table lamps. This PorkPie Table lamp is the only one that has a stumpy pressure tip, its almost flush with the tank. The last photo below is how they should look tall, not stumpy. Could this of been hit and been pushed inside re-soldered, or am i being paranoid. It’s just funny that out of 15 PorkPie Table lamps this is the only one like this with a stumpy pressure tip that only protrudes a little from the tank. Remember the last photo is of a normal looking one that I put up for comparison.
