Value of an MM sidevalve engine?

[RobThomas]

I've got 2 engines here that were rebuilt with new oversize pistons and had ground cranks etc. Things like new valves and timing chains went on and then they got dry stored. I've no idea what they would cost these days to rebuild. Anyone got any suggestions as to value? I guess I could ask A-Series Spares???

My first thoughts.

Fully fitted out with ancillaries, or short engines?

Any of the reconditioners will have prices which will almost certainly require the old engines as part exchange - so possible added cost there.

Would you offer a warranty?

Location might even be a factor.

There may be other thoughts ...later.
