Really interesting thread, guys.
I have certainly never seen a taped weapon in a Tri-logo, sealed bubble. I have only been collecting them a few years but it's a well known feature that the weapons aren't taped, as folks have already mentioned.
Oracle, welcome to the forum, mate. You've got some lovely bits from your childhood. Kudos to you for keeping them! However, I am discounting your two examples of taped weapons for two reasons: Firstly, they're open. Memory plays tricks on us and we humans are fallible! The fact they're open does preclude them from being evidence of taped weapons. And 2) The weapons are taped on the wrong side. Sounds like a funny thing to say but the only time I know if weapons being taped on the right hand side of the bubble (as you look at it) is for IG-88, Cloud Car Pilot and I think Luke Jedi(?). The common feature there is they all had two weapons/accessories to hold.
As for that Chripa. Hmmm. As mentioned the lines are common enough. I can't see anything that screams reseal but I have an amazing IG-88 Trilogo reseal that doesn't look like one. The tape says reseal to me but if in doubt ask the question of the seller, buy it (although it's at least twice the price you should look to pay for Chirpa in Trilogo in that condition!) and then you have ample grounds for a return. If it isn't a reseal it's a very cool trilogo variation
