Ex-Reference Models for Sale

Over the years, we have amassed a large collection of reference models - models that we keep and refer to when we need to build more copies of the original. With changes in the way that we work, these models are no longer needed, so we are selling them off at a huge discount. This is a one-off opportunity to buy some of our models for very little money - and if you want to buy a large number of models in one go, we're open to offers. We don't want to disappoint anyone but, in order to be fair, the models will be sold on a first-come, first-served basis. You are welcome to reserve items for 24 hours to give time to check finances and place orders, etc. Please email [email protected] to put in your request.

The list may be downloaded as an excel file here.

The model sizes have been subjectively classed as small, medium, large, or v. large - this reflects the cost of the model as much as its physical size. So, a model may be physically small, but if it has a high density of bonds, it will be more expensive and may be classed as 'medium'. At the same time, a physically large model with a low density of bonds may also be similarly priced and also classed as medium for this purpose.

The condition of each model is classed as vg+, vg, good or fair. These are fairly subjective classifications.

"vg+" is a model that we would not be able to distinguish from a new model

"vg" is a model whose balls are structurally sound and which looks good, doesn't look new to us as we recognise the ball colours as from previous batches.

"good" indicates a model that is in reasonable condition, but showing some age.

"fair" indicates a model that is quite aged and possibly faded, but is included for interest.

The type is simply a guide for whether the model is a mineral, a biological model, or used for crystallographic teaching.

The notes are partly for your benefit and partly to remind us of some issues that need to be dealt with if the model is sold. Reserved items will be held for 24 hours before being relisted as available for sale.
