Hello. I purchased a collection recently which had 2 strange variations I have never come across and I wondered if anyone had any information about them. First up is a Gen1 Whirl. There was only one Whirl in the collection yet I have 2 complete sets of accessories, one in black and one in dark grey. Now it could easily be a figure got lost but I have never seen the dark grey accessories before and I was wondering if anyone had ever come across them before and what their origin is. The Megatron is even stranger. It had a complete set of accessories but the silencer section is not made of 2 seperate pieces, it is one solid molded piece. Again I was wondering what the deal with this oddity is. Thanks in advance for any help.
