One of my pet projects for the past few years has been an attempt to kit bash the old Revell 1/130-something scale
USS Asheville class gun boat model of the USS Defiance (PG-95) into something with a better weapons fit. Finding suitable parts and pieces has been a challenge as there are very few ship models in comparable scale or that are compatible for that matter.
I toyed around with modifying an image from the reference books to see what a Defiance class would look like armed with 76mm Mk75 automatic guns and I must say that it looks quite enticing.
A decent (but not quite the same scale) source for parts to tart up the Revell Defiance kit can be found in several 1/144th scale kits that are now available such as the Revell of Germany Leopard Class (Type 143A) and Albatross Class (Type 143) Fast Attack Craft model kits or even the USS Fletcher kit for a nice little kit-bashing with a dash of scale-o-rama for added zest.
