I recently purchased an old Stubben Parzival dressage saddle for my daughter. I contacted the company and said the saddle was made before computers. 

The leather on the knee flaps is scaley and cracking.  i used the stubben oil products and it did soften it up.  Does anyone know anything about saddle care and is there anything else I can do.  I don't want to do a restoration because that is expensive. 

Also,  any idea what it is worth.  it is made in germany.

Thanks, karen
