Excellent analogy.
Was the primary source quoted?
Also may I ask who authored that particular Osprey book? (Unfortunatley it matters with Osprey at times.)
Hmm, on checking the book -- which was this one:
http://www.osprey-publishing.co.uk/title_detail.php/title=P6035
-- it ain't there. You're right, they do vary in quality and I found a couple of errors in the above one, though it does have some extraordinarily cool anecdotes.
I picked it up and read it on a trip to Malta in 2002, so I'm now guessing the extra-pay-for-one-handed-bastard-sword-use factoid comes from my visit to the National Armoury of Malta on the same occasion. Though this was a major-league museum with loads of cool arms and armour (Malta is well worth a visit for anyone interested in history, BTW; stone-age goddess figures and megaliths, Phoenician shrines, and major invasions/wars from around 1500 to 1945 or so, including late medieval, Napoleonic and WWII), the written descriptions of the kit were sometimes rather scanty. I'm pretty sure the bastard sword quote comes from there, though.
My other favourite factoid garnered from the museum was that though the Siege of Malta took place in the 16th century, supposedly well into the era when guns had supplanted bows and crossbows, there was a major use of crossbows during one day of the siege; the Turks decided to mount a major assault in heavy rain, reasoning that though neither side's guns would work, they had the weight of numbers. Grand Master Valette ordered the armoury's stock of by then antique crossbows to be issued, and the attack was thereby repulsed for the day. (Some days later in the fighting, Valette, then in his seventies, was woken by a successful breach; otherwise unarmed, he grabbed a morion helmet and pike, and led an even more successful counter-attack).
Ah -- bit of a digression there. In any event, that museum was the main place I've seen where the bastard sword is mentioned as being used one-handed on foot; most of the time, it's used one-handed from horseback, or two-handed on foot (as in Talhoffer). I was able to write this into the weapon stats for Conan, in which a war sword (= bastard sword) is a martial weapon if used either two-handed, or one-handed from horseback, but is an exotic weapon when wielded one-handed on foot.
