GM328A tester

I got a GM328A tester from eBay, only to receive it broken because the seller ship it in a plastic envelop.
the rotary encoder with switch was snapped in two.
I wander if anyone has the part number for it or can give a link to where I can buy one?

there are many on eBay all looking physically the same but with different functionality.(i think)

Claim a full 100% refund from the seller, it they refuse start a claim in Ebay, done this a few times because of similar problems

i did get my money back,
they don't want the broken back so if i can fix it i can use it.

These things give amazing functionality for the price that we pay.

did mods...
did add banana female sockets, it gives now possibility to use all kinds of probes from testers.
glued a piece of broken drill into the lever of micros socket. the lever was short to use.
