OCSI.
I almost finished the SP3.
I have had problems because the lack of many pieces in the model.
I scracht builded many of these with "ever green" materials, however my undercarriage is not a beauty.

There were all the pieces in your box ?
About the squadron I have some picture of the SP3 and the predecessor SP2, but all with different squadron insigna, really I do not understand that insigna ( white star in red circle).
