Hi guys,
Have anybody here built FLAGMAN's 1/350
U-boat Type VIIC 41 (kit number 235003) or
U-boat Type VIIC special version (kit number 235022)?
I am curious how large (in mm) is decal #28 in kit 235003:

or decal #12 in kit 235022:

It is Frontreif symbol I need for my XXI U-2536.

Can somebody help me out, please?
Thanks.
