I am clearing out my late fathers workshop which is proving a huge task.
I found on a shelf today my old Post Office Respirator No. 1A. It is/was a very good dust mask with a pre filter and a cartrige second filter. All packed up in a gold coloured tin, we called a tea caddey as it looks like one. The filter in this one is dated 1991 and we had to change these frequently and bin all stocks older than 1 year.
I would like to continue to use but clearly it is out of date. Inside the tine were the Post Office instructions for use P1 Gen S5160 dated 1977. The instructions say Respirator No. 1A Baxter Pneuseal.
Any idea where I could get a supply of filters?
I note there is one complete unit on Ebay for £40.
