Help! With fiona seed drill

[will_mck]

I've a fiona seed drill, its an astra dr model and I've reconditioned the drive chains which are contained inside the 3 plastic chain and cog casings between the metering wheel and seed drill gearbox. The problem is I've only had 10 minutes at it now and again over the summer and I must have stupidly rebuilt those 3 plastic boxes in the wrong order because when drilling wheat the other day it was sowing twice the amount I'd calibrated for. I know the problem is that I've those plastic boxes the wrong way round somehow. Should have taken pictures before dismantling

Anyway, would anyone have picture or a diagram of the order of these parts? I've rung Jim Price machinery for help and I'm waiting for an email with a drawing but I don't think they're having much luck. Some of the newer models have numbers written on each end of the case to indicate the teeth on the gear within

Thanks, much appreciated. I found the manual in a filing cabinet since. I'll share this if it helps anyone else in the future

From my neighbours machine, unsure of exact machine type.

Hope it helps
