I followed up on the lead regarding Hama bottles as a Jobo 1000 ml substitute. I think the original Jobo bottles are no longer available new and the used ones are pricey.
I found them on this website in Germany:
They are also pricey in US dollars but I tool the plunge and bought a dozen of them because shipping was a little better at that quantity. They arrived today. The are just like Jobo bottles. They fit perfectly in a CPP of TBE. The lids are wider which I think is better. I have not checked the lids for being spill-proof. So these are an excellent alternative to the Jobo 1000ml bottles and readily available. Thumbs up.
