I recently bought an OM40 fitted with a 'power winder' from Jessops. A few weeks later I bought a mint OM1 MD which has the facility to take a power winder/motor drive. My question is; will the 'Jessops Power Winder' work on the OM1? The reason for asking is because the OM1 has a little cover over the mechanism on the base plate that doesn't look the same as the mechanism on the OM40 and I don't want to ruin a perfectly good OM1 for the sake of putting an unsuitable winder on it, which I'll probably use very little if at all....just curious!
