Checking my receipt it was 18 count, apologies my memory slipped!

They say "Hi-Vi Research" on them.

I got them from Larry along with my mids, I imagine they're the same as those he's selling on ebay currently.

ACOUSTIC RESEARCH AR-3A TWEETER REPLACEMENT-REAR TERMINAL CONFIGURATION | eBay

I like them, though I've never heard an original 3a tweeter to compare to, only a 2ax

I'm thinking of filling them up with some dark filler then seeing how they look and assessing how to disguise the blemishes from there.

I didn't receive any original grilles for them, the pads added were for larger grilles that I've discarded. I bought some hardboard today for making new grilles as shown in the third picture but I've yet to find measurements for cutting out the inner section.

I can obviously take an approximation from looking at pictures of the originals but if anyone has measurements or a technical drawing that would be much appreciated.

I ordered (edit) 18 count Wichelt linen which has yet to arrive, I'm hoping I can get the hardboard in shape by the time it does.

Finally, the only other question I have is does anyone know where I could get replacement crossover caps cheaply in the UK? Everywhere I've looked is hella expensive.

Thanks!

This is a picture taken today of AR3a front cover. Note that the outer dimensions as the height and width includes the thickness of the fabric front. Hobe this can help you.
Check the inner dimension on your AR3a before cutting the fiberboard.
I don't know where to find cheap bipolar capacitors.....but Jensen bipolars are fine substitutes for the original Sprague.

Ps.You can find some AR3a info on my amateur site
