You may be confusing the DynaBass ,which Tim Landers helped design, with his TL-5. The DynaBass and the 1st generation TL-5 share the same electronics and bridge. However where the DynaBass had both Schaller tuners and Schaller 3D bridges the 1st gen TL-5 only got the Schaller bridge.
Neither 1st or 2nd generation TL-5s had 'open gear' tuners, always mini tuners like Gotoh GB-7 & GB-707. They may have used actual Gotoh though it's not guaranteed, Peavey used Korean Gotoh copies for their premier model the US Cirrus.
For the 2nd generation TL-5, Peavey moved from the Schaller 3D to an unbranded bridge. I'm almost certain these were sourced from ABM in Germany. The black bridge on that green bass is an ABM bridge or a copy of one. Peavey used those bridges on the Cirrus and some later year 2nd gen TL-5s shipped with them.
Reason for the change was more practical than economic. 1st generation TL-5s had Peavey's Super Ferrite pickups. Designed for 4 string basses, they were not quite wide enough for a 5 string bass π The Schaller bridge allowed players to tighten up string spacing for a more even signal. The 2nd gen came with an actual 5 string pickup which rendered adjustable string spacing obsolete π
There's a good chance that green bass has a stock bridge and tuners.
The 'rugby ball' jack socket plate is an addition, the original bass had a Switchcraft barrel socket. Like all barrel jack sockets it will have failed and I imagine some damage occurred while replacing it; hence the cover plate.
Knobs are 1/4" (6.35mm) solid shaft for the Vol and Balance, 1/4" with 1/8" top shaft for the tone pots. If any pots fail I would look at replacing the entire EQ rather than attempting to solder new pot to the PCB.
Looing at your photos I think somebody has already tampered with the EQ section. You should have 2 dual pots, Hi/Low and Mid shift/Mid +/- . Could you provide a photo of the control cavity ?
OP's bass is from early/mid 90'sπ
