ANA 45
ANA tells me it's North American Aviation (P-51) by origin
45 is the year it was manufactured
Can't place the part at all, my guess is that it's an internal panel

I agree with

Rocketeer
- that is not a NAA stamp. They vary but are typically as shown. Also, as he says, 45 is the individual inspectors number, not the date of manufacture.
As Rocketeer says those are not North American part numbers - all of which start with the model number and a dash, followed by a five digit component number (followed by a dash and additional numbers in some cases). For example, from the P-51 parts cattledog. You will notice that this model 106 aircraft contains parts from the model 73. This is normal as the model 106 is a modified model 73 and only the parts newly designed for the model 106 have that prefix. Both the 73 and 106 (and many other models including T-6 and B-25) include parts with a 16- prefix which means they were originally designed for the NA-16 basic trainer but were still in use on the later aircraft.
Likewise although the part numbers look similar to Spitfire numbers they are not Spitfire for several clear reasons.

- First the letter prefixes that Spitfire parts did not have. Eg PC and PD
- Secondly they lack the component number. EG 33158 123 indicates item 123 of major assembly 58 for design 331. On the Spitfire the numbers in the circles are the component numbers. In this case 33027 with 330 meaning Mk I and all following aircraft that use this exact part, 27 meaning fuselage and 2045 and 2046 being the component numbers of the individual brackets, left and right.
- IF Spitfire 331 would indicate parts related design 331 which is the B type wing. 58 indicates the major assembly number (eg 27 for fuselage) but there is no major assembly 58 on a Spitfire. The wing itself is major assembly 08 so wing parts start 30008 for a Mk I and newly designed parts for a Mk V (design 349) wing start 34908. Again parts from a Mk I still in use on a Mk V or Mk 24 still start 300.
