I grabbed the first pic off the pinside thread for the new DE repro trough board, board protector has slots on side to access switches and balls in trough, game was Last Action Hero. New repro board is taller, guy had to add spacers between pf and protector, which is already weak being made from extruded plastic if I remember correctly. It's not gonna survive too many impacts/pf drops.
Second pic posted later in this thread, it's different with only small holes to access the switches.

I can't find a part number anywhere in any DE manuals like TFTC LAH and TOMMY.
I plan on getting stronger repros of the protector with the slots made.
If someone has a spare lying around to sell please lmk, Thanks!

Nope
That's just the ball deflector on top of the trough.

Thank You for the offer to send, but hold onto it for now, as I see it's DIFFERENT from the pic I snagged above. Yours only has small holes to access and test just the switches, the other has longer slots I'm guessing to access the balls as they rest in the trough. So there's at least TWO versions, once I get the other one eventually I'll maybe give you a shout for yours. I will have my new repro board in by then, so I will know if it needs to be taller to fit that, or just add spacers as mentioned above and repro one version.
The plastic is thick since it IS possible to rest/drop the playfield directly on the trough switch board, which is crazy. I remember the one on a previous crypt being extruded plastic, which would not last more than one or two impacts, so a repro needs to be stronger. We've got several smart arcade/pinball laser/3D Print repro peeps here in central florida, so when the day comes I'll get with them to come up with the the best solution.

EDIT: nevermind the edit

BUMP-date...

Sonic (first pic) confirmed his 'protector with slots' does not have a flange on back with screw mounting holes, just like GRB1959's 'protector with holes' (second pic). So I'm guessing all protectors just had the one front flange for mounting. Looking at my un-protected TFTC trough-board area, it SEEMS like a rear flange could be added. Still looking to buy one with slots to run around with to show potential repro-er makers, LMK if you have one for sale!
