The Lledo Cataloguing system by RDP Publications indicated that LP models are those with a tampo printed artwork finish. The numbering system is simple and consists of the prefix letters followed by the model type as below. The next three digits refer to the livery name. The suffix letter would signify any variation to the original livery, for example a variation in colour. The suffix letter "X" indicated that the models were delivered to the client for their completion.
To ensure that these run in order we have had to add an additional zero at the beginning of the Lledo Reference number on some of the models. The search facility should still pick up the model without this additional number.
