I'm afraid you can't sell them on here as you are not a regular contributor. Also our members are model makers rather than purchasers.
Generally speaking amateur made ship models do not command very high prices these days and specialist auction houses such as Charles Miller are unlikely to accept them.
Museums don't want them either as model exhibits tend to be rather out of favour at the moment.
The usual method of sale is via Ebay which will enable the models to be seen by the most people and offers the best opportunity of mazimum sale price and a good home. It is where most buyers will look.
