A couple of months back I built a new bellows for an old Lachenal 48-button English concertina, and I think it came out rather well. I used the methods outline on the Homewood site, and my thanks goes out to Bob Tedrow for his excellent instructions. The bellows that were on my squeezebox were not originals, and they were functional but very ugly. Finding the papers was difficult, but the ones I got from Concertina Connection worked out fine. I'll attach a couple of pictures for your inspection.
