Applying for Naturalisation- ILR sticker on passport, NO BRP

[coolbidder17]

Hi,

I am about to apply for naturalisation (British citizenship). My ILR is on my (old) Passport and I currently don't hold any BRP.
However, an earlier Tier1 extension was issued as Biometric card. Though when I applied for ILR, Home Office issued ILR as a sticker on passport and did NOT returned the Biometric card.

My question is while filling the naturalisation form (version 02/2017) , section 6 i.e Biometric enrolment states:

6.1 Have you been issued with a BRP with a previous application for leave? Yes go to question 6.2 No go to question 6.16

Unfortunately I am unable to find a record of my Tier 1 extension BRP.

Can you please help with below queries and advise, if -
1) statement in 6.1 refers to ILR only and thus I need to fill it response as NO.
2) I need to state that I was once having BRP (on a previous visa extension) and fill in relevant sub section which I have no record of and thus provide an explanation of why I don't have.

Logically I think it should be referred in context with latest immigration entry and thus NO.

Also, if I'm referring as NO, should I even mention (in additional space regarding an earlier issued BRP on Tier 1 extension and me not having any record of it ?)

Really appreciate your advise.

Many Thanks.

6.1 Have you been issued with a BRP with a previous application for leave? Yes go to question 6.2 No go to question 6.16

Grammatically, with the inclusion of the word "a", I think the question refers to any one of your previous applications.
