Nice work! I've been curious about how many Orients and other 20 holers are still around. Compared to the 25s, they seem a bit more scarce.

I've always liked the tower games added to the 20 holers starting with Orient. Really interesting challenge.

Yes, all the red should be 55. I paint with acrylic and simply hold them upside down then dip them into red paint. Clip them up somewhere to dry and you've got a nice red letter bulb.

As okorange mentioned, the circuit is perfectly balanced for a #47 and a #55. Any combination of other bulbs will malfunction (more than one red letter lit, no red letters lit, etc). Also, this is the only part of the machine that required the use of a #47 from the factory.

Sorry Frank, the red bulbs go behind the title only. There are two bulbs for each letter in 'orient'. The actual feature of the red letter can use a 47 Orr a 55 (plain).
