A question for the G1 experts on the board, I've come across a boxed G1 Megatron in good condition that I'm looking to purchase. It looks to be a "pre-rub" version and the stamp only says "MADE IN JAPAN TAKARA" on it, no dates or mention of Hasbro.
The box looks like a US one with the small Hasbro logo on the front, bottom left.
Any alarm bells going off with any of the above or does it all sound good?

Edit: looks exactly like this one
