Historic Tug boat

Apparently this is the Bonchurch - one of the last of the TID tug boats originally commissioned for the D-Day landings - although this one was only finished in 1945.
She is - or was - up for sale for £18,500 - and may or may not have been/is being converted intoa houseboat

Basically she has been moored on the bit of canal for ages - and getting her out and back onto the Mersey would require going through a canal lock.
She must have come in this way - but it would be a tight fit!!!
