Big anglo in Instrument Construction & Repair Posted August 10 · Edited August 21 by RP3 Kim, I Too have big hands and find Lachenal and Wheatstone concertinas generally too small for my hands. But Crabb, Ball Beavon and Jeffries concertinas work just fine. Surprisingly, the sizes of these three brands is usually about 1/4" smaller across than the Lachenal and Wheatstones, but the button layout on the Crabbs, etc are more open. This is what helps with big hands, not the overall size of the instrument. In fact I am more comfortable playing my Jeffries than a Wheatstone sized concertina. So unless your hands are really much bigger than my "farmers hands", concertina size is not the issue. Now, if you are sure you want lots of extra buttons, then size can be an issue.
