Can anybody help to identify the gearbox fitted to my Gardner 3LW? It is cast iron and weighs a ton but nnfortunately the last remaining label was unreadable. There seems to be a casting date on one of the castings of 18-3-77.

unfortunately this forum is not really suitable for this type of question because you can not post large, detailed pictures. I suspect it might be a Parsons box but it is only a guess. Perhaps the best thing to do is to join the Canal World Forum (Google "Canal World") and then post the picture and question there, I am certain you will get your answer within days, if not hours.

An update for other readers. Steve did as I suggested and with a couple of hours had the box identified as probably one by Twin Disk. A quick Google in images produced a photo from a company in New Zealand where the peculiar features of this box confirmed its makers. Tony Brooks

It got even better with a subsequent email that not only identifies it as a Twin Disc but also the model, case style, mounting and potential ratio :) quote "Twin Disc MG-506 shallow case it appears to be adapted to SAE1 housing, ratio unknown but could be either 1.5:1 or 1.97:1" Thanks again Steve
