Hello All, got the low-down on the Sloper from George Sheads' Villiers Parts site. If you go to the 'contact us' section, there is a really decent selection of pics to help you ID your old English Banger. I've got parts from there too, and while not cheap they are true old new stock....really top quality. The manuals for the Marquis are from Ivor Gregory who runs the UK site 'Old Lawnmower Company'. I got the illustrated parts, operating instructions and detailed workshop manual for the engine as one PDF package sent by e-mail. I've passed this on to Bruce so it will soon be availabe to anyone else tinkering around with a Marquis. I've done a lot of global searching for old workshop manuals recently and believe me the $15 subscription you pay here is an absolute bargain.
