I have a 1959 Union Armera / Grulla box lock M205E.

I have 3 questions:
1. Is there any listing or information on Union Armera & Grulla models by year?
2. As I have tried to determine (for Insurance purposes - NOT Selling) the value of my gun It appears that a Grulla box lock is priced significantly less than a side lock, currently there is a Union Armera
box lock, 20 gauge for sale at William Larkin Moore & Sons for $2000.00 which is almost half the price of any Union Armera / Grulla gun listed on Guns International. Why?
3. Was the 205 or 206 the only box lock models Union Armera / Grulla made?

Any Information would be greatly appreciated.
