Allis combines were very popular in Britain, they had a high reputation for reliablity and for producing a clean grain sample. They were the best combine for harvesting grass seed. The feature of the bottom of the concave dropping open if there was a blockage or a stone entering over the header was unique and invaluable. This one belongs to a farmer & collector who uses it to harvest a small acreage every year.
They were fitted with Perkins diesel engines.
Another one that has survived into preservation.
The old combines here rusted out and 99.99% were scrapped over the years, only worth the value of the engine & the driving wheels & tyres.
Today there are a few enthusiasts who are starting to collect them. Its a big lump to restore and to transport around shows!
The last combines built by Allis here was the 5000 in the late 1960's, but by that time sales of NH, Claas & MF had the market sewn up with a better dealer network. I cant even find a photo of a 5000 on the internet
