PzShreck -> B-10 RR
I'm not sure how justified some of these are, but it gets the job done I guess.
The B-10 RR was a Soviet 82 mm smoothbore recoilless rifle (hence "RR") that had been introduced in 1954, and which served as a dual purpose weapon.
It could fire HEAT rounds (with relatively large wing stabilizers) with a muzzle velocity of 322 meters/second, AND it could also fire HE frag grenades in indirect fire mode (pretty much like a mortar) with a max range of 4500 meters.
The East German Army [NVA] introduced it with the designation RG-82 (R = "rückstoßfrei" =recoilless, G = "Geschütz" =gun).
In turn, the Panzerschreck had a really low muzzle velocity, its grenade had to exit and travel 2 meters until it actually reached its max velocity of 105 meters per second, and its (halfway reliable) max. range was ~180 meters (where some German/Swiss sources say 400 meters, based on training results using Panzerschreck derivates produced after the war and used in the Swiss Army, IIRC). Also, the Panzerschreck's grenades just had little fins, no wing stabilizers like the B-10 rounds.
So, in case you're using the estab data of the Panzerschreck for the B-10, then you won't do the RR justice.
I'd advise to use the German 7.5 cm Leichtgeschütz 40 ("light gun"), which should be in the COTA estabs, since that's a recoilless rifle/gun, and adjust its values accordingly.
EDIT: With that solution, there will be no indirect fire mode, I guess, unless the lG 40 underwent the same change as the le.IG ("light infantry gun") guns, which Dave made after a discussion about the IGs dual purpose capabilities.
The IG guns were actually triple purpose guns: indirect fire [main purpose] with HE, direct fire with HE and antitank-role (the production of overcalibre AT hollow-charge rounds for the le.IG.18 started around 1940, already, the guns' AT capabilities turned out to save the day in North Africa quite some times).
I remember that I had a discussion with Dave about the recoilless lG 40 guns, back then, but I can't remember whether the gun actually made it into the estab or not.
I think he (or one of the Panther bunnies) argued that the gun shipment didn't make it to Crete, due to the convoy being attacked by the Royal Navy (and returning to port), or something like that.
Interestingly, there are pictures showing 75mm lG 40 guns in action .... on Crete :
Anyway, the German 75mm lG 40's rounds used 75mm field gun HE rounds (weight: 5.8 kg) and HEAT rounds, too. With HE rounds, the lG 40 had a range of 6500 meters. Muzzle velocity: 345 m/sec.
Weight of the gun: 270 kg for the mountain division-version, 175 kg for the Fallschirmjäger-version.
The effective AT-range of the B-10 was ~400 meters (107mm B-11 RR = 450 meters) and the max range in HE frag-mode 4500 meters (107mm B-11 RR = 6650 meters). The best AT round could penetrate 240 mm of armor.
The AT round of the B-10 RR had a weight of 3.87 kg, 4.11 kg and 4.9 kg (3 types), the 2 different types of HE frag rounds a weight of 4.9 kg, each.

Quite funny looking thing , hehe.
