Lachenal Duet On Ebay: Strange Serial Number

[greno35]

This concertina on ebay http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewIt...me=STRK:MEWA:IT

 

is given with the number 8875

 

If we look at different formulas to calculate the date of fabrication we found between 1953 and 1969

 

Is it possible that this number is OK?

in my experience, it is very easy on some lachenals to confuse the '8' with the '3'. This could be what has happened.
