The firmware on Zimmers FTP (and everywhere else) are 901484-03 and 
901484-05. Indeed those are indicated on your own site as belonging to the 
2031LP, but on the other hand they're also mentioned in the 2031 service 
manual. There was a discussion on this list earlier this year where both 
Ethan and Ville mentioned that their drives had those ROMs, without 
indicating they would refer to the LP version specifically.

I suppose it takes unscrewing a drive to check for sure. xAD/nIGHTFALL 
already did in 2015 and posted some pictures, but unfortunately one can't 
read out the ROM numbers:

While we're on the topic of that site, here is an article on how to refit a 
VIC-1541 shell to a 2031LP drive:
