I think that thinking is not possible without some assumptions.
But as logic ''prescribes'' if the assumptions are false then
all deduced statements irrespective of their ''logic'' will be
also false. As is, I assume, well known ''our Lew'' has always
some assumptions irrespective of his ''familiarity'' with the
given ''subject matter''. I have no idea why he assumed that
I sold my B-60 replica. The case is that I bought two samples
after my email exchange with the seller. My problem with my
sample was the ''steel pin'' which lead the up and down movement
of the construction. I asked the seller (producer) if I can get
this ''pin'' little bit bigger and made from ''gun metal'' . By his
answer the seller also told me that he will stop with production
because no profit whatever he could made. I got my ''gun metal''
pins bu also bought his last sample. So I still own two samples.
I changed the steel pins for ''gun metal'' kinds and also substituted
the sticky synthetic oil for (smooth) grease.
So thanks to my own improvement I am now satisfy with both my
samples (grin).
