thank you so much don!

anybody have a download link for a digital version of this font?

You're welcome Danny. The design is used by a British house number maker -- can't recall the url but if you dig with Google it should be findable -- and they provide only a very small scale jpeg image to assist buyers. [I increased the scale and enhanced it for my post.] Clearly they want to keep the design as a business asset.
