No problem :-)  just keep the partial file, & do something like this:
localhost:
	mv cvs-cur.1500A.gz cvs-cur.1500A.gz.1x
	ls -l cvs-cur.1500A.gz.1x
	-rw-r--r--  1 daemon  wheel  12345678 Dec 29 20:09 cvs-cur.1500A.gz.1x
	dc
	12345678
	512
	/
	p
		24112
	dd if=cvs-cur.1500A.gz.1x count=24112 of=cvs-cur.1500A.gz.1
	rm cvs-cur.1500A.gz.1x
freefall:
	dd if=cvs-cur.1500A.gz skip=24112 of=cvs-cur.1500A.gz.2
	ftp cvs-cur.1500A.gz.2 to localhost
localhost:
	cat cvs-cur.1500A.gz.[12] > cvs-cur.1500A.gz
to get :
	47140400 cvs-cur.1500A.gz

The alternative is of course to use ncftp in append mode, but I've never 
done that, & would tend to distrust a core dumping program to leave a nice 
uncorrupted tail on a prematurely truncated file,
I suggest if you go the append route, you keep a careful note of your first
ls -l size, just in case you need to fall back on dd :-)
