I then thought "I'll have a look in the forum and see what people are saying about their & other boxes" - a less formal level of review if you like - and I found that those discussions lived amongst the General Discussion area, not a separate dedicated one.
Dedicated areas are great, except when folks ignore them. Many C.net members seem to start new Topics in the "General Discussion" sub-Forum, regardless of their content. E.g., they'll ask a history or repair question in GD. Other times such a subject will be a digression from the original subject of a thread. Occasionally, I'll make my reply to such a "misplaced" post as a new Topic in what I consider to be the appropriate sub-Forum, but most folks don't do that. Then there's the question of where to put a Topic when it crosses categories. E.g., should I post something about my 19th-century concertina tutor under "Concertina History" or under "Teaching and Learning"?
Your best bet is to use the Search facility (maybe with "More Options"), in spite of its limitations and the masses of hits you'll get on certain maker names.
But with few exceptions, each instrument is unique. Even those models that were mass produced (or produced in batches under Wheatstone) are likely to show significant differences in sound and feel simply because of differences in how they've been used, current condition, or who has restored them.
Of modern instruments, the Morse models and Concertina Connection's "Jackie" and "Jack" are pretty consistent, and the Stagis, Scholer's, etc. seem to be consistent in the inconsistency of their mechanical quality, but Tedrow, Suttner, Marcus, etc. tend to do at least some customization of each instrument they make, something that I think is most often evident in terms of sound. So it would be misleading to review such instruments in a way that suggested, e.g., "
this is what you can expect a Geuns-Wakker anglo to feel like and sound like." The more useful review is to comment -- as many have done -- on the general quality and the extent to which it met the buyer's specifications.
Something similar goes for vintage instruments. No two Wheatstone Ĉolas that I've owned -- or played -- have sounded or felt quite alike. I have a Lachenal Edeophone English that not only sounds and feels quite different from my Lachenal New Model English, but also from Edeophones I've tried in the past, even two others with the same amboyna ends and glass buttons.
In the end, the only way to be sure is to
try a particular instrument before you buy. And to try several of each type to develop your own sense of general quality and variability.
