I bought a C/G Clover anglo concertina kit from Wim Wakker in August, 2012. I finished building it in December, 2012, except for fine tuning.
It cost 1450 dollars including a gig bag and the shipping cost.
Layout : Wheatstone layout.
Reeds : Italian accordion reeds
Bellows : 6 fold bellows
Ends : Flat Wood ends
Keys : 30 metal keys
It's responsive, but not so responsive as Edgley concertinas. As you know, Edgley concertinas are much more expensive than Clover kits.

I had received an email from Wim Wakker. He wrote "When key travel is adjusted to 3mm and the reeds set correctly, you'll find that the Clover is much more responsive."
So, I adjusted key travel from 4-5mm to 3mm as he writes in "Manual for the Clover anglo kit".
Thanks to Wim's advice, my Clover is much more responsive! I think it's nearly as responsive as Edgley now.

I quickly recorded a set of two reels on my Clover concertina.
And I asked my wife to play a tune on it.
I sold this concertina in 2016.
