I'm posting this for Buzzbait, his material is on the Worldnet web server:
S! all
Here is a page from a USAAF document on a P47-D21. It details weights and various loadings. You can see from this the Razorback P-47 is considerably lighter than the later models.
Attached also is this photo of a P-47D. It's not a Razorback, but I think a Razorback in these colours would look pretty spiffy. It's a 78th FG Jug.
