This looks anglo, but I am not sure, might be duet...

Or may be this one ?

Is there any possibility of Erinoid?

Maybe it's a new concertina maker. https://www.facebook.com/BodandBox-Bodhranfr-469216453285747 or http://www.bodhran.fr/index.php/fr/

According to this article http://www.concertina.com/chambers/lachenal-production/ Edeophones were made between 1889–1933. But you may want to ask in "Dating A Lachenal From The Serial Number" thread to find out more precise year.

Thank you for the in-depth review and playing Cohen. I received my duckling from Paul a few months ago and that was my first Bflat/F. Compared to Lachenal, The button spacing is slightly wider(please see photo), but I got used to it soon. I am very happy with it.

That album is found on youtube, probably uploaded by TOPIC Records. https://www.youtube.com/playlist?list=OLAK5uy_kBScS9byE7NVXUNDS89btd6uY2DZDrP7Y

Concertina Museum have 2 Crabb Englishes (Ref:C326 and C327) https://www.concertinamuseum.com/CM00326.htm https://www.concertinamuseum.com/CM00327.htm I also recall a large (9 inch across according to the description) twin reeded English with red bellows and straps made by Crabb was on ebay in 2011. I didn't bid on it but looked like specially made one.

Sorry for the thread drift, but I just noticed that ButtonBox now lists #33301 on sale. https://www.buttonbox.com/concertinas-in-stock.html

I once saw a 20-button wooden ended Crabb on ebay in 2017, which had metal plate with serial number. For example: These pictures were from ebay and I did not bid on it.

It looks strange. The Lachenal's reedshoe trademark is on the other side. And the ends look handmade. But the action looks like Lachenal's hooked type.

How about Harry Geuns ? He is based on Belgium. https://bandoneon-maker.com/jackie-and-jack/

Here, for example. https://concertina.co.uk/stock-selection/anglo-concertinas/gorgeous-lachenal-32-key-anglo-in-bb-f/

I too think the Lachenals with pierced sides are rare, but not non-existent. I saw Barleycorn once sold the Lachenals with pierced sides at least 3 times.
