It appears from what I read that you need to have an approved reason for storing these and collecting is not sufficient reason in your country, though such is allowed elsewhere, even over the border in Belgium, but a museum in your country would be allowed to store and display them. I suggest you contact museums and have them take these internationally important and not to be destroyed items and display them on long term loan from you. Such can be displayed in other countries. Museums are about preserving valuable pieces of history and should jump at the chance, especially if you have aviation museums there.
Also is there any law in having these items removed from Holland ? Try museums outside of Holland. Even collectors outside of Holland. I know of one in Belgium. Get it written down as to who has ownership...i.e. you. Collectors will be glad to provide a service to preserving what are historically invaluable items. Items that are allowed outside of your country if they are in a safe intact state. There is also mention on Key Publishing forum of a replacement glass that will render them safe.
Ownership of these is not illegal, having them not in a museum in your country is, so make arrangements to have them resited elsewhere. The museums or collectors travelling to where they are now held to remove them out of Holland or into Dutch Museums.
You are but a keeper in this timezone of items which must be preserved. These are of international significance and your local police should not have the power to destroy items of this importance just because they were sited in your house. Pay the fines and plead ignorance. State that you were building up a finite complete item before seeking museum display opportunities, as no museum would want a part project.

Hope these ideas help you. I shall personally be outraged if the authorities there destroy such historic items when safe display is but a sensible level headed phone call away. You were not holding these so as to use them in a deliberate way to cause harm. They should focus their attentions on the more seedy side of life in Holland, on people that are a pain in the side of society there and not on individuals who unknowingly have broken a law, a law that is not even existing in other sane countries. They the authorities would be displaying levels of irresponsibility, not you. They would be the criminals. Who were you harming, yourself. Perhaps they can shoot you for harming yourself ! Certainly the emotional and financial damage they will do to you will be more harmful than the harm of keeping intact instruments. Certainly though any damaged ones or those with dust from contact with broken ones should be removed and cleaned in an approved way or disposed of as such. Sensible cleansing with correct protective clothing, approved glass replacement etc will render those items valuable enough to warrant this displayable again.
Get a good lawyer. These are items that are ok to be sited in some buildings in Holland, just not your premises, simple, get them moved. Re-possess them but away from your premises and sell some to ofset lawyer costs. Make sure the authorities are aware they must be seen to be sensible about this and take part in the resiting of such historical items, otherwise others with such in their possessions will be frightened to rehouse them, they will disappear into attics etc which is counter productive to the authorities aims and where more harm can be done according to them, though the danger to neighbours would appear to be nil anyway !

One also wonders how many you are allowed to have, would one be ok ? I am aware of large pocket watches that have Radium on their faces, do the police also burst into watch collectors houses and seize such ? wartime watches can have celluloid faces, surely thats less protective than glass ? Its the radium thats illegal, not the instrument, so if watch collectors with such are legal, you may try for a loophole in the law there. I have also seen WW2 army compasses with radium on the outside, are they illegal ? Is a collector of jeeps in your country also going to be pounced on, their instruments contain radium I see according to forums. Your lawyer must get these resited and the case laughed out of court if similar collectors are still legal.
