System OID for Routerboard 750GL?

OID_Example.jpg
We are working with HP on their Network Automation Product and they are creating a driver for us. Can anyone tell us what the “System OID” is for the 750 running 5.26 firmware? HP keeps saying we are providing the wrong OID but all we can find is this “system.sysDescr(.1.3.6.1.2.1.1.1.0)”

Any Ideas?

TIA

I Did a snmp walk and this is what they needed in Red

OID=.1.3.6.1.2.1.1.1.0, Type=OctetString, Value=RouterOS RB750GL
OID=.1.3.6.1.2.1.1.2.0, Type=OID, Value=1.3.6.1.4.1.14988.1
