Compare your tube layout to determine if you have an early or mid chassis:

If an early chassis (p-p 45's) you need an H-2 speaker. A mid version (single 47) uses an H-3 speaker.
There is a guy on eBay that sells pretty good reproduction tube shields:

You might also want to look for a pair of copper Mershon filter capacitors to re-stuff and replace the two modern replacements on your chassis:
