Many thanks for the gallery records. I think you were the first to record the Jensen and Morwell machines. I had never heard of them.
There is so much we are not likely to know about Swift foundries.
There are some things I don't get. It's more likely Pope acquired the Swift foundry for other manufacturing purposes - not necessarily the manufacture of lawnmowers.
That Pope decal on the Supa-Swift presents as a rushed job. The Pope-SS's must be rare.
