After 50 years in hibernation and some speculation over provenance it's now safe to say that the chassis featured in this blog is without question a Yimkin. The discovery of a series of Kodak slides from the 1960's reveal that not only is this a Yimkin chassis but that it was the stable mate of XYN160 and sat beside it on trestle tables from 1961 to 1963. So a huge thank you to everyone who has generously shared information. So, what is the story behind this chassis?
Is this one of the 6 Yimkin chassis that has been canibalised... it seems very unliekly this could happen as early as 1961?
Is this a 7th Yimkin chasiss that was never completed and was later canibalised to create the chassis as it stands today?
Please take a look at the photos and let me know what you think...
