I do not have inside photo currently. But I believe it has 22 button originally (not modified from 20 button) and have English type construction not German one.

It might be a 42-key chromatic anglo described in Jones' 1884 patent. http://www.concertina.com/jones/index.htm

The fretwork reminds me of Jones too. But 7 buttons in a row looks unusual to me. In the photo above the 6th button has riveted action but 7th one (and air button) have hooked action. So this might be a result of a modification.

The article is here but in the archive.org. I too think the Lachenal formula is outdated. I recommend to post an inquiry to the "Dating A Lachenal From The Serial Number" thread for more precise information. Taka

I now own the one described above. Celestial means double reed tremolo tuning according to the Dan Warroll's article here.

I don't know if I should upload it but I archived a photo from ebay 2016 and it shows separate reed chamber and enlarged(doubled) pads.

I think the first one was filmed in Japan, at Birdland Cafe in Kanagawa, not in Okinawa.

That one in the photo has similar bellows papers to my old Bastari.

According to thesession.org (please see the last comment from Jason himself), the composer of this tune is Fabio Colussi. http://fabiocolussi.altervista.org/index.html

Update: They say overseas shipping is now available, with newly designed items. https://jabaraparty.official.ec/categories/1213877

Or you can use this contact form to John Dipper. As mathhag said, with the serial number I think they can provide details. http://www.johndipper.co.uk/concertinas/contact.htm ?

Does it have "Louis Lachenal" label or "Lachenal & Co" label ? If the latter, it might be 114949 (leading 1 missing) or 14949X. I once saw the photo of 15130 (slightly later than yours) which had "Louis Lachenal" label and numbered keys. That was with 20 buttons though. ?

Just FYI, about Mrs. O'Dwyer (The Irish German concertina project by Dan Worrall (archive.org)) and review of the resulting project CD ("Tripping to the Well" (mustrad.org.uk)) ?

MP4 and PDF work fine here. Thank you. ?

Same here. Returns Error code: 2S328/1.

End grill is not an Edgley because Edgley instruments have end bolts on the corner. The instrument in the clip looks like Jeffries anglo to me but I may be wrong.

I think some model of Lachenal and Wheatstone have such slots for air levers (bowing valve?). But I am not sure they only have slots or they have actual levers. For example (from buttonbox.com), Lachenal: https://www.buttonbox.com/images/ceu0558-02b.jpg Wheatstone: https://www.buttonbox.com/images/ceu0557-02b.jpg

Number stamps reminds me of these pictures. So could it be a Tidder ?

This reminds me of Wakker midi (archive.org), but it seems to be discontinued. ?

I am curious about action improvement. The Button Box of Massachusetts also says (from some months ago) about Stagi W15-LN as "30-button model with new improved action." I am not sure the improvement is the same but would like to see the improved action photos. ?

One example ...... https://www.instagram.com/p/BsCRTPtneL9/

If I understand correctly, ESB is a baritone(1 octave below) and Cormac plays both baritone and bass(2 octaves below). I am not sure the one in the clip is a baritone or a bass. As far as I know, Dipper makes bass anglo. ?
