I have 4 we use in a commercial shop operation and the are tough and easy to use Kenneth
At least I can see across the shop when I'm done. :)
The local independent shop had some t'other day, but the owner did say that he'd had a bit of a run around to locate any wholesalers that had stock. Lee
Theres a shop there that is main UK distributor. Get on phone off ebay and call. Great people to deal with. I buy in 50's usually.
hit a model shop and get some tranlucent iron on film. Solarfilm. Most of it will stick with a tad of solvent as well..a light brush with celluluse thinners..
Remove the old one, take it to a proper plumbing shop & get a direct replacement.
better still but a decent 'delta peak' nickel cell charger from a model shop. charge times around 20 minutes are the norm: faster than that overheats the cells a tad.

Personally I find it bonkers in a country that makes it almost impossible to buy H2O2, or isopropanol, you can buy explosives in any corner shop this time of year ...
If you are in such a small shop that the owner's there, it's almost certain that you can buy cheaper online :) which is probably why internet shopping is so popular.
