I bought a H. Crabb & Son anglo concertina through eBay last month. It seems to be made circa 1951.
It has traditional concertina reeds. I don't know any other concertina makers that used traditional concertina reeds in 1950s or 1960s.
I think there were high-end Crabb concertinas that were as good as Jeffries around 1900. But this Crabb isn't so responsive though it's worth the price. I guess it's as good as a Lachenal that I had before.
Because it had some flaws, I fixed them.
First, I attached felt to the reed pan and the bellows frame so that air doesn't leak from gaps in the reed chambers.
Second, I adjusted gaps between the reed tongues and the reed frames using Tuning Bellows.
Third, I tuned the fourteen reeds that weren't in tune, using Tuning Bellows and files. It took about half a day.
Fourth, I replaced the old pads.
Fifth, I replaced old and worn-out hand straps.
It took about two days for me to repair this Crabb. I enjoyed repairing it very much as usual.
I played a set dance using this Crabb. I like its tone.
