I had also noticed the same issue .
I am going to go with a genetic clubman chainset . It has
A 110 bcd I will have to change the 50t outer ring to a 44 .There are plenty available. The inner is a 34 lso that works for me . The design is quite retro so another plus .

Never seen a Simplex mech like that before. Is the dropped pivot home made? Disraeli gears has a facebook page so might be an idea to contact him.
