Some recent finds

[Alex Rice]

Hi All
Some recent finds, with some questions:
1 - Early RAF senior NCO's badge - Can you confirm it is RAF and not RNAS?
2 - Early RAF officer's cap badge.
3 - Looks like a WWII economy badge, cotton embroidered. It has the date 12-?-44 written on the back. I've never seen an example like this before, any info on it? It has holes in which look like somebody fitted a metal eagle over the embroidered one, which has been removed.
4 - Unusual padded example of a WO's badge.
5 - Clerical badge - no idea but am told it is RAF.
Thanks for any help in advance. Cheers,
Alex
