It reminds me of a pattern you might find on a manufacturer web site. I think a lot of shops will use the free manufacturing patterns when creating kits...keeps the cost down.
Is it similar to a one block wonder, but with 4 rather than 6? If so you would need to fussy cut identical blocks for each section. other than that it looks like 4 patches on point. Disappointing there aren't more instructions, but at least it shouldn't be too hard to put together. It will be beautiful once you get it done!
