Service respirator No. 10 development and trials documents

Currently waiting for a response from Ministry of Defence, they should respond promptly and normally no later than (details).

Dear Ministry of Defence,

I'm trying to do some research into the S10 respirator including the development and 1982 trials. I'm just wondering if the MoD has access to these documents and would be willing to disseminate them.

Yours faithfully,

Piran Malvern.

Dear Dstl FOI,
Apologies for being somewhat vague, I'm interested in the field trials of the S10 along with any development documents associated with them. And thank you for your response.

Yours sincerely,

Dear Dstl FOI,
My apologies for not making my request clear enough, im interested in the initial development and trial documents starting from the first concept if they are available to just before the 1986 start of mass production and replacement of the S6 respirator im sorry if i can't make it any more clear but there is absolutely no currently existing information online that i can find to narrow it down.

Yours sincerely,

Piran Malvern
