Hi Leo, I have one long case Home ser#H92952 w/original crank and here are some photos with measurements. The crank measurements are hard to read but the OAL is 2.980(75.69mm) and the depth of the slot is .250(6.35mm) I hope these help. BillF

Dear Leo
The two longcase Homes have winding shafts of 187mm length overall, diameter 6.9mm. The pin which engages the crank is 20mm from the end. I checked the Suitcase Home as well, and this has a shaft of the same dimensions. The Standard A shaft is entirely different, and only 93mm long.
The only difference I can see is that the Suitcase Home's crank stem is shorter than that for the long cases, at 37mm (vice 72mm above). This clearly isn't the problem, and nor is the use of a later motor as this would have a threaded crank shaft.
One small point. From youre photo, the wooden top frame looks very wide. Might that have been replaced at some time? On my Longcases the top width at the crank end is 50mm, and it projects about 9mm out from the side of the case. Could this be the problem? Could either this be a new top, or the top replaced off centre so that it projects too far to the right?
Other than that I am now stumped. It might be worth measuring your shaft and if it is vastly different either driull a hole fpr a new pin closer to the end of the shaft or get a new shaft/chassis from croskinfrog or similar, which wouldn't be prohibitively expensive. Sorry - does anyone else have any ideas?

well guys I don't know what's wrong with my stuff... I get all the same measurements.
and what about the distance between the motor frame and the side of the bead plate frame? my motor seems to be further to the left than your's maroongem. I measured mine at 2 9/16
