Sleaford Navigation
Hi Steve, I have written quite a lot of the article about the Sleaford Navigation. Do you know if the information about the lock sizes is published anywhere? Both Skempton and Boyes & Russell mention that they are 60 x 15 ft. Wikipedia is about verifiability, so without a source, I would not want to alter it. I note that the infobox mentions that the current size is 70ft, and Cumberlidge confirms that. I was hoping that your website might mention it, but sadly that doesn't either.
