This is for the R26 model 2-2641, should be nearly identical. The seller is a great guy.

I included a parts list for the 2-2651, there were no drawings, your best bet is to buy the eBay manual and compare it to the parts list in the picture

Thanks for the welcome! I'll go post something in intros after this. I'm a bit further down the country that you: I'm just outside Nottingham.
I had a good look on that site and other parts of t'interwebs for a manual. I must be looking in the wrong place as I've yet to get my paws on an actual chassis guide or similiar. I can find one for attachments and the engine, but sadly, not the bit I'm looking for. I've been searching using the R26 or 2-2651, but no joy as yet!
As to a photo, would a video be okay? It's not the original engine, but everything else seems pretty old school. What happened to the original engine I've no idea, but given the age of the mower, I'm impressed by the build quality. BTW, apologies for the lawn damage: I'm going to give my two rescue greyhounds a firm look to killing the grass off :-)
