Sub insert identification

[nigelUK]

Appreciate some expert help identifying my bezel inserts

I've had the spare (No.1 in pics) for quite a while and was thinking about selling it. I attempted to swop it out first to see what it looked like in my sub, but was unsuccessful and reluctant to risk damaging it (and my thumbs ).

Anyway I've had it for a long time but never really inspected it close up. Realized it is a little different from the one I have in my Sub (No. 2 in pics)

I've tried in the past to get my head around insert identification
Struggle with it to be honest ..

Would be great if you guys can identify these for me and will also help with me valuing No.1 if I decide to sell it.

My sub is a late 1680 (circa 1980) .. I've always thought the insert (No.2) was a 'mid-font' .

Thanks in advance ..
