I'm having a few issues in getting a replacement part for the 1/24 scale Spitfire Mk Vb. ( A50141) The part is the instrument panel/ bulkhead that several other parts attach to. This part on my instructions does not show a part number ( Section 4) 3 times now I have received all the attaching parts,which i did not request or need. Could anyone please tell me the part number that I would like to order. I have even sent a highlighted photo of the item to the spares team, but to no avail. Many thanks Paul Sargeant Airfix Club Member
