Tell Me 'bout this Insert

[jtiis]

I've got this Rollie insert I don't know anythign about. Someone gave it to me some time back without details about which model she came from. Standard sub - or - something else?

 

Thanks...

Looks gen, just from the back... could be wrong though

 

Its fairly beat up

Yes, gen. Didn't know if its a common version or something to treat with xtra care. She has seen better days that's for sure.

Looks gen to me.

Like a 16800/early 16610 tritium "Flat 4" insert.

Nothing uncommon or "ultra-rare" about it.

(though it also looks to me like someone has swapped pearls at some point.)
