I think I know the answer but just to clear things, are Wiretap 1st and 2nd gen lenses the same

[Funky-Trixtar]

First, Second and Third Gen Wiretaps(all with the same frame and offset lens configuration) have the same sized lenses? Thank you.

To my knowledge, there is Wiretap, Wiretap (New), and Wiretap Rx.
Lenses are not interchangeable.

@flyer, there are two versions which look similar: the only differences that I know about are the earstems(which point down directly as opposed to an angle) and earsocks which are a different shape and larger at the ends.

As per this pic illustrating the differences.

@PapioXmetal, hope you don't mind me using your pic.

I knew there were different socks, and ear stems (Halfwire) but have never noticed those drooping "wing tips" before...
My four Wiretaps all have the "perky" tips.
Never stop learning stuff here.

Top lens looks taller.

I agree, it does appear to be taller but was wondering whether this was just a 'foreshortening', which can occur at certain angles with photos: I'll ask @PapioXmetal.

I'm sorry I am no help. All 3 are out the door and I did not measure them..

Thank you, Dave.

Edit: I've messaged FGG, who may well have the answer.
