Vintage Buffet Crampon Clarinet 1954 R-13? #46058 France For Sale

This has been in my family for over 50 years and was last played around 45 years ago
It\'s been stored in its case indoors since
I do not know anything about clarinets, but have tried to provide plenty of photos at top of page and below
It will obviously need going over, new cork etc.
The serial number is #46058 which, according to the research I did, should date it as being made in 1954
It\'s marked \"Buffet Crampon A Paris\" and \"Made in France\" (it was difficult to get a good photo of the logo)
One article suggested this could be a R-13; I\'m sure anyone interested in the clarinet will know if it is an R-13
The Brilhart mouthpiece is marked with a \"3\" and with what looks like \"119017\" and is scuffed up
The case is a very interesting, old case, rather beat up
If there is anything in particular you want me to check, send an email and I\'ll get back to you ASAP
