Crown and tube for 1655

[Hkpilot]

Hi, my very first post.

Pls let me know if anything inappropriate.

I’m building a 1655 and have question about the crown and tube.

I found that I need the B24-600-0 crown. But there is also different number on the packing on some Ebay auction. Such as G1, MI-05, JR-07, H-12, etc for the same model number.

Similarly, for the 24-6020 tube I’m getting, there are numbers such as X-03, P-03, AL-07.

May I check whether I should research some where else before paying?

Thanks and sorry if this has been asked before.

Bump in case someone knows the answer.
