I think you will find the kits are for the BN and BL versions of the car although the flexible hoses could well be the same after a certain year and type 11cv, 15cv after -1936. 7cv tend to be different.
What I have done in the past is send the originals to a company and they reproduce them exactly – length and fittings. The same can be done with the copper brake pipes if you cannot manufacture them yourself.
I am in Cardiff.
