It looks like Steellbow to me too - though the 'e's are very tall ...
My searches turned up the following - irrelevant, I'm sure, but sort of interesting.
Steelbow: "A condition of land-tenancy whereby a landlord provided the tenant with stock, growing grain, straw and implements under contract that the equivalent in quality and quantity should be returned at the end of the lease"
The above from the online Dictionary of the Scots Language.
