Hi Bill,
I have a little story about that piece. When searching online a few
weeks ago, I saw the ad from Andys Arcade that featured that part.
The ad claimed only one left so you know I quickly place the order. A few days
later I get an email from Andy telling me that the item was
previously sold and inadvertently not removed from the site. Geez what a
disappointment! Yes, that display seems to be really rare compared
to other displays that are sought after. I haven’t been able to even find a
mention of an SP-737 anywhere online, except for Andy’s. Will keep on
looking but I want to thank you for your effort on my behalf. All the best!
