A friend of mine who is altering and converting his 00 gauge railway, kindly gave me some of his unwanted models, which was very kind of him. Two are by Collector Club, is there anything extra special about these? they are; R3775 Network Rail 0 4 0 diesel shunter 2019 collector club by Railroad, the other is R2597 Class 0F 0 4 0 ST Queen Elizabeth II 80 Collector club ? Just curious. Thank you.
