My gosh I horded way too much crap. Plastic dip tube but screw on/off retaining ring and bung hole in side for inspection. You may be able to replace dip tube assembly with a metal one - I never checked. I'll ship UPS or USPS - you pay actual shipping.
This sat outside for a spell, thus the dirt inside pictured in pic 3 (through the bunghole... I love that word).
