Has any user of this tank here in the UK found caps that will fit the Stearman SP-445 developing tank, perhaps from a soft drink bottle etc? I had a mini panic today when I couldn't find one of mine and I realised that I was vulnerable and need a backup. I'm ordering some from Stearman but in the interim I was hoping someone's had better luck than me trawling through discarded plastic bottles. I've searched through posts on the site here to no avail - but that might just be me!
Thanks
