And now look at that thread McBob started about his Mac 73 with stamped numbers in the same place and starting with 47-
Following on what Marshall said above, there must have been a bunch of fast changes happening at 6101 Century Blvd during that time of transition from 47 to 49 to 73... people scrambling to come up with the prototype for the big meeting with Mr. Mac on Thursday morning...
I can imagine some R&D engineer telling his secretary, "Oh, while you're at lunch, stop by the art supply store on Santa Monica and pick up a set of 3/4-inch stencils..."
Well, boys, it's a half-hour later and I've got all the lettering for the airfilter cover. There are two coats of yellow over the original paint on my airfilter cover, So far, I've carefully removed most of one, and parts of the middle one... without damaging the original at all...
The early Sunday School kids stared at me through the window of the van, standing out back of the honeyhouse in a pair of old moccasins, levi's, no shirt, with a big yellow chainsaw on the table, gently rubbing on it and staring at it close-up... Maybe one or two wished they could come and see what I was doin', instead of havin' to go and sit still and be clean while listening to Sister Chaney tell 'em about Elijah and tha Fiery Chariot... again...
My 49-33 has the block numerals. The text on the airfilter cover says:

So, Tom... your 49-1 may be the only one with that style of numerals...
and also... notice that one of the pix you posted above may show a 49 with black filter cover and yellow numerals...

But that may have just been the Mac Art Department's work when making the brochure...
