RH "Beatle" Bass, Hofner, model 500/1

I bought this bass guitar in 1967.  I played it for about 6 months and it went into storage for the next 43 years.  Its been stored in my home and office and in storage facilities.  Throughout its existance its been kept in environmentally controlled facilities.  I also have the original case.  Some of the adhesives are cracking on the case but it is still in great shape.  No adhesives problem with the base.  I did, however, oosen the strings about 10 years ago to relieve the tension on the neck.

I want to sell it and I've seen posts on the Internet that place this insturment between $1500 and $2500.  I posted it for $2500 on the Base Museum but have received no queries.  I read that Hofner did several productions of this model and some of the sellers are advertising the old model with the new purchase date.  Stuff like that has me puzzled and uncertain as to value.  Any help would be appreciated.
