As per title. Is it 4 3/8 LP ports and one 7/16 HP port, also is the 22 with removable hp crown? Cheers.
I think there may be possibly two varieties of the model. I bought a used one with a DIN fitting so there was no yoke knob to verify if it was actually a 22 or not but it has 4 3/8 LP ports. It also has a removable crown. The 2001 Parts Catalog shows the possibility of two models one with a removable crown and one without. I am pretty sure the differences between the 21, 22 and SE2, SE3 models was the 1/2 LP port/hose which at the time was considered and upgrade for better breathing.
