OT a bit.
Can I find out where did you buy the model and how much did it cost?
The fast/strike packs available arent' for the 25th anniversary valks
Yup there isnt many strike part specifically for the 25th anniversary but from pictures I believe its possible to mount the super strike parts for the 1/48 model on them considering the only difference between the 25th and non 25th is the color scheme.
That aside, I will probably purchase the YF-19 next month and post some photos here too
